Thirty - three time of year and 662 episode of theOne Chicagoshows — Chicago Fire , Chicago PD , andChicago Med — have aired sinceChicago Firepremiered in 2012 , and through it all , we have had to reluctantly say adios to many beloved characters . None of the three series ' casts appear the same as they did in their several first seasons , which is a sad but graspable verity . Most actors only stick with a show for so long before wanting to explore other opportunities . Consequently , some characters have died , while others have merely moved out of Chicago to exempt actor ' absencesintheOne Chicagouniverse .
TheOne ChicagoTV series premiere on Wednesday , September 25 , on NBC , withChicago Medseason 10 premier at 8 p.m. ET , Chicago Fireseason 13 at 9 p.m. ET , andChicago PDseason 12 at 10 p.m. ET .
Some oftheOne Chicagocharactershave been harder to say goodbye to than others . It ’s much easier to have go of those who only stick around for a season than eccentric who have been around since a TV show ’s beginning , specially if the writers pour down them off in the fabricated creation . However , when a TV franchise likeOne Chicagolasts a long time , actor exits are to be expect . Nevertheless , I’m still support onto hope that some depart ( and alive ) characters fromChicago Fire , Chicago PD , andChicago Medcan returnto their various series one day .

10Matt Casey
Chicago Fire
Jesse Spencer ’s Matt Casey was arguablythe face ofChicago Fire , which is why his release in season 10 was so shameful and upsetting . Spencer was one of the original main cast member of the NBC adjective drama , and his character ’s role at Firehouse 51 made him all the more important . Casey was the police lieutenant in charge of Truck 81 . His leadership acquirement defined much of the work ethic among the firefighters , butCasey ’s time on the show would cursorily end duringChicago Fireseason 10,when he move to Portland , Oregon , to take care of Andrew Darden ’s sons .

Thankfully , Chicago Fireseason 10 , instalment 5 , was n’t the last time we saw Casey in Chicago . Casey return for Kelly Severide and Stella Kidd ’s wedding in the season 10 finale and then again towards the end of time of year 11 when he came to the city on business . DuringtheChicago Fireseason 11 coda , Casey proposed to Sylvie Brett , and she said yes . The two wed in season 12 and moved to Portland , provide the Windy City behind .
However , the room access remains open for Casey and Brett ’s yield , which ( at least , in the fictionalOne Chicagouniverse ) is very plausible once Casey is no longer the Darden boy ' defender . countenance ’s just hope that Spencer is receptive to repeat his part inChicago Fireone day , and Kara Killmer is right beside him when or if he does . Chicago Firehas lost too many characters as of belated , and make for Casey back would be a welcoming gift for many fans .
9Sylvie Brett
Speaking of Brett , Kara Killmer leftChicago Fireafter Casey and Brett ’s wedding in time of year 12 , episode 6 . It wasa bittersweet good-bye as Casey and Brett finally get their happy ending , but that also meant that viewers had to bid farewell to both characters for the foreseeable future . Even though Killmer was n’t a part of the original cast ofChicago Firelike Jesse Spencer , she was one of the veteran players on the NBC television serial . Brett was introduced as Leslie Shay ’s replacement in Ambulance 61 in season 3 , and she stick around Firehouse 51 for almost ten time of year .
I ’m still holding out hope that both Brett and Casey can revert to Chicago one day and rejoin their phratry at Firehouse 51 .
Brett quickly became afan - favorite character inChicago Fireas she is well-fixed to love . Her cheerful yet professional personality was perfectly balanced , particularly on a show that experienced a mint of heartbreak . So , it ’s good to say thatBrett has been affectionately omit since her exit . As mentioned above , though , I ’m still holding out Leslie Townes Hope that both Brett and Casey can return to Chicago one twenty-four hours and rejoin their fellowship at Firehouse 51 .
8Gabby Dawson
Perhaps this is a controversial opinion , but I would be intimate to see Monica Raymund reprise her part as Gabby Dawson inChicago Fire(especially with Casey and Brett go ) . Raymund was amongthe originalChicago Firecastmembers , and her fictitious character was one of the best during the early seasons . Of naturally , everyone knows thatGabby started to go downhill in the episodes leading up to Raymund ’s exitfrom the NBC adjective drama . However , a piffling buyback never pour down nobody .
Stellaride is not out of the woodwind instrument yet – a new update concerning Chicago Fire time of year 13 points toward more problems for Stella and Severide .
It would be intriguing to seeGabby return to Chicago and Firehouse 51 for a bit of a redemption arcin futureepisodes ofChicago Fire. Now that Casey and Brett are gone , Gabby would have a little more room to suspire on the show . We would n’t have to worry about a insistent and agonizing Gabby / Casey / Brett love triangle , andChicago Firecould just focus on Gabby outside her love life . Raymund ’s return toChicago Fireis more like a pipe dream than a reality , but that wo n’t barricade me from hoping it will happen .
7Erin Lindsay
affect on toChicago PD , the firstChicago Firespinoff has also lost many actors since its premiere in January 2014 . PerhapsChicago PD ’s most devastating passing was Sophia Bushas Erin Lindsay . The actress was among the original cast of the NBC constabulary procedural series , and her character was quite meaning because she had ties to several characters . Hank Voight was practically Lindsay ’s foster Father of the Church , she concisely dated Kelly Severide fromChicago Fire , and Lindsay and Halstead were one ofChicago PD ’s most interesting couples to rootle for . Unfortunately , Bush ’s prison term on the show had an exhalation date .
Lindsay had a rough upbringing that plain carried over to her maturity . She receive multiple heartbreaking departure , includingthe last of Nadia Decotis inChicago PDseason 2 . Plus , Lindsay ’s mother ’s drug addiction cover to weigh to a great extent on her , so much so that she afterwards accepted a chore at the FBI in New York to have charges against her mother send away during the season 4 conclusion . The chance of Bush regress toChicago PDis almost next to none , butshe ’s doubtlessly among the most missedOne Chicagocharacters .
6Antonio Dawson
Jon Seda ’s Antonio Dawson was among the tec and officers in the original Intelligence Unit crew inthe cast ofChicago PDseason 1 , and he stuck around for six seasons before leave . It ’s been a long prison term since we saw Antonio ’s face in the NBC procedural series , and his replication would be exciting . Antonio served as a worthy resister to Voight regarding their morals , get their dynamic quite entertaining . Unfortunately , it ’s been difficult to replace Antonio ’s purpose regarding his relationship with others inChicago PD .
Jon Seda joined the cast ofChicago Justiceas Antonio Dawson during its first ( and only ) season , but after its cancelation , he return toChicago PD.
Perhapsif Gabby ( Antonio ’s babe ) returns to Chicago , Antonio can , too . Like many others on this inclination , though , a miracle would likely have to go on to have Gabby and Antonio back in theOne Chicagouniverse . However , a one - instalment cameo might be possible . Maybe a lot of actors can hark back when theOne Chicagofranchise hit 700 episode ( or if it makes it to1,000 episodes likeNCIS ) .
5Jay Halstead
Jay Halstead ’s exit fromChicago PDis probablyamong the saddest departure in theOne Chicagofranchise . Like Sophia Bush and Jon Seda , Jesse Lee Soffer was inChicago PD ’s original cast and a fan - favorite character from the very kickoff . However , Halstead ’s send - off in season 10 was quite controversial and many conceive it was a ill turn to his character . As a result , it would be ideal if Soffer could recapitulate his role as Halstead in a future episode ( or episodes ) to give his character the occlusion he deserve .
Unfortunately , Soffer in all likelihood wo n’t be returning toChicago PDanytime soon . Soffer was cast as Wes Mitchell , Scott Forrester ’s replacement inFBI : Internationalseason 4 , which will premier in October 2024 . It ’s more than likely that the doer will be busy withFBI : Internationalfor a while and wo n’t have fourth dimension to get back toChicago PD . But Soffer has admitted that he would be open to returning ( which he did in seasons 10 and 11 as a director ) , so , anything is possible .
4Will Halstead
Jay Halstead ’s brother , Will Halstead , is anotherOne Chicagocharacter who is dearly missed in the franchise . Nick Gehlfuss leftChicago Medonly one time of year ago , but his character ’s presence is always welcome in the aesculapian drama . Will was an integral member ofChicago Medwho had been work at Gaffney Chicago Medical Center since the beginning . Of course , he could be frustrating at times ( just like most ofthe otherChicago Medcharacters ) , but it ’s unmanageable to swallow a reality where Will is n’t in the idiot box serial .
Three seasons after Torrey DeVitto exited Chicago Med , the NBC aesculapian dramatic play series has finally discover someone to replace Dr. Natalie Manning .
Will leave Gaffney Chicago Medical Center duringtheChicago Medseason 8 finalewhen he give in his missive of resignation , frustrate with the new policies at the infirmary . Gehlfuss ' character then moved to Seattle to reunite with his ex - fiancee , Natalie Manning , and her Word , Owen . It was admittedly the perfect ending for both Will and Natalie . However , that wo n’t block me from hoping the couple returns ( even if it ’s a abbreviated cameo ) toChicago Med .
3April Sexton
April Sexton is arguably one of the most underrated character inChicago Med , which might be a controversial opinion . However , she deserved a lot better during her sentence on the NBC medical play . So , it was belike for the unspoilt thatApril leftChicago Medin time of year 6 , but selfishly , I want to see her recurrence to the show . It feels like April ’s story is n’t done , and that ’s probably because it was never pass the right care it deserve .
[ Yaya ] DaCosta claimed she would riposte toChicago Medon one condition — April becomes a doc .
Yaya DaCosta catch the prospect to give closure to April whenshe returned inChicago Medseason 8 and conjoin Ethan Choi . Of course , seeing them get a happy ending is fulfilling in and of itself . But , we still missed out on really seeing April and Ethan as a married yoke and how their dynamic change ( if at all ) . The good newsworthiness is thatDaCosta claim she would come back toChicago Medon one condition — April becomes a Dr. . That seems quite manageable to me .
2Ethan Choi
If April returns toChicago Med , Ethan Choi would have to , as well , and I would receive the two original series regulars back with undecided arms . April and Ethan ’s romance was one of the unspoiled in the NBC medical dramatic play , and the idiot box show is in dire motivation of a just romanticism asChicago Medheads into its 10th time of year . Plus , as mention above , witnessing April and Ethan ’s dynamic as a marital yoke would be very challenging .

Outside his relationship with April , Ethan was afan - favorite graphic symbol inChicago Med. While every other doctor was breaking the rules , Ethan was following them to a tee ( sometimes to his detriment).Brian Tee ’s persona was unlike all the others inChicago Med , and having him back would be like a breathing time of fresh air . Perhaps Ethan and April take what they have learned from their mobile medical clinic and apply it when they give to Gaffney Chicago Medical Center .
1Connor Rhodes
It has been a long time since we have seen Colin Donnell ’s Connor Rhodes inChicago Med , which is quite a disgrace given how dear he was in the show . Rhodes left Gaffney Chicago Medical Center at the beginning of season 5because he want a smart starting after Ava Bekker ’s death , and Donnell has n’t reprised his role in aChicago Medepisodeever since . Maybe Rhodes ground what he needed during the five - plus years he has been away from the hospital , and he ’s quick to return in a next episode ( or two or more ) .
It ’s knockout to deny thatChicago Medhas gotten increasingly worse as the season go on , but the riposte of Rhodes ( or Will , April , or Ethan ) could be just what the TV serial needs .
Donnell returning as Rhodes inChicago Medwould be quite a surprise , given how long he has been away from the NBC aesculapian drama . However , the actor reprising his function would doubtlessly invigorate the show . It ’s hard to deny thatChicago Medhas have progressively uncollectible as the seasons go on , but the comeback of Rhodes ( or Will , April , or Ethan ) could be just what the goggle box serial needs .
