8Joe Cruz (Joe Miñoso)

Chicago Fire

Cruz is one of the most recognizable brass inChicago Fire , which makes his exclusion from theOne Chicagocrossover disappointing even though there is a good intellect for it . When Cruz got shot during the robbery he was wedge to take part in , it led to widespread guess thatCruz was leavingChicago Fire .

NBC has a very important reason for interchange the schedule and begin the One Chicago crosswalk with Chicago Fire rather of Chicago Med .

Instead , after he squeal , Cruz was suspended for two weeks for his out or keeping behavior . It would n’t have made sense to make an exception to his punishment so that he could appear in theOne Chicagocrossover , so Cruz remained off - cover during the peculiar event .

7Kylie Estevez (Katelynn Shennett)

No real explanation is given for Kylie ’s absence seizure . However , it ’s unsurprising she is n’t included since she appears only periodically inChicago Fireseason 13 . That said , when Kylie was missing fromChicago Fireseason 13 , sequence 6 , it could be explained by Engine 51 not being have , while her absence seizure from theOne Chicagocrossover makes far less sentience .

Hermann ’s most salient squad member is missing without explanation .

Hermann ( David Eigenberg ) has a fair large office in the crossover , as he tells Pascal that he wo n’t be able-bodied to live with himself if he stays above basis lead his team instead of helping with the rescue effort after Kidd is trapped . Still , Hermann ’s most salient team member is miss without explanation . One can only presume that Kylie is part of the rescue team despite not being seen on - covert .

6Jack Damon (Michael Bradway)

Jack Damon ’s recent replication toChicago Firehelped make up for his unnecessary exit earlier in season 13 , but it would have been nice for him to have a cameo during " In the Trenches . " While he does n’t work for Firehouse 51 anymore , Damon is still in the area .

It would have been fitting for him to offer up Severide reinforcement while Severide was wait anxiously for news program about Kidd ’s status . unluckily , Damon is not even mention during theOne Chicagocrossover , so there is no account for where he is or why he did n’t reach out to his half - chum .

5Deputy Chief Charlie Reid (Shawn Hatosy)

Chicago PD

Althoughthere was no genuine understanding to admit Deputy Chief Reid in theOne Chicagocrossover , he is an interesting case whose presence would have tot up something to the story . He might have involved himself in the crisis , especially the conflict withChicago Med ’s Lenox , as part of his program to countermine Voight at every turn . There likely was n’t room in the activeness - packed episode for him to slip in himself . That said , Dick Wolf Entertainment and NBC have not given any official reason for his absence seizure .

4Naomi Howard (Ashlei Sharpe Chestnut)

Chicago Med

Naomi often shadows Lenox , who has to encourage the medical scholarly person to be more self-assertive and take hazard so that she ’ll succeed in the tight - pace world of emergency medicine . However , she is prominently missing from theOne Chicagocrossover .

No account is given for Naomi ’s absence seizure . However , it ’s easy to imagine that she is overshadow someone in another department or at her medical school class during the crisis .

3Sam Abrams (Brennan Brown)

Amazingly , nobody hits their head or has any other reason to necessitate a neurosurgical consult during " In the Trenches , " so Abrams remain off - screen . This is dissatisfactory , considering thatthe window pane - tongue neurosurgeon has some ofChicago Med ’s funniest lines . TheOne Chicagocrossover dealt with heavy topics , so it could have used some of Abrams ' cutting , yet hilarious , mention to break up the tenseness .

2Nina Chapman (Sara Bues)

Assistant State Attorney Nina Chapmanis the perfectChicago PDcharacter to calm Voight down when he conk out too far . Her bearing might have helped Voight deal with his battle with Lenox without resort to empty terror . However , Nina go forth townspeople after installment 4 , andshe ’s not set to come back untilChicago PDepisode 15 .

it would have been a nice bonus if Nina appeared during the crossing to support Voight and keep him from getting out of line in his efforts to shut the case .

Nina ’s absence is thwarting because her story with Voight is bare . Of of course , this will be continue when she returns to Chicago . Still , it would have been a dainty incentive if Nina appear during the crossover to patronize Voight and keep him from get out of line in his efforts to shut down the case .

1Wallace Boden (Eamonn Walker)

Boden leftChicago Fireat the end of time of year 12 . However , he supposedly train a promotion and is now the Deputy Fire Chief , so it ’s ridiculous that he is n’t involve in the gas explosion crisis . The crisis should be concerning not only to average people , but to everyone who runs the metropolis of Chicago , include the Fire Commissioner ’s office .

fire station 51 responded to a major emergency brake that put some notable role at risk , and despite that , Chief Wallace Boden still did n’t seem .

Boden ’s absence is more understandable than most , however , Pascal is running Firehouse 51 inChicago Fire . Thus , Boden probably would n’t want to step on Pascal ’s toe by engage over , specially since Pascal is still a relatively new chief . That said , it is a boastful release for theOne Chicagofranchise to have to do a crossing without bring back its most popular former character .
