Chicago Fire dealt with a malicious intruder in Until The Weather Breaks. Find out what happened in our Chicago Fire season 7, episode 19 recap.
The latest Chicago Fire episode proved that Firehouse 51 really does have an open door—which once again came back to haunt our favorite firefighters and paramedics.
Wednesday’s installment “Until The Weather Breaks” saw a young child turn up at the firehouse, not telling anyone who he was or how he got there. It didn’t take long to deduce that something terrible had happened to him, while the team also tried to fend off the person responsible.
Elsewhere, Stella Kidd (Miranda Rae Mayo) once again butted heads with Emily Foster (Annie Ilonzeh) about Stella’s ex-boyfriend, while Chicago Fire might have been dropping a hint about a new couple in the making. Maybe.
Click through this slideshow to find out what happened in the latest Chicago Fire episode for each of your favorite characters, starting with:

An unexpected houseguest
It’s pouring rain outside Firehouse 51, which allows Foster to admit she’s planning to blow off a date with a woman at Firehouse 90. Sylvie Brett (Kara Killmer) says she thought the woman was straight. “So did she,” Foster replies, before commenting on how Brett was good with Kyle.
She returns to the common room, where everyone else is wasting time waiting for the rain to let up. Matthew Casey (Jesse Spencer) wants to jump a random plane to anywhere; Kelly Severide (Taylor Kinney) tells him that’s how he ends up in a Turkish prison somewhere. Touche, Severide. He’s not wrong, either.
And then the power begins to flicker, adding some extra drama to this Chicago Fire episode, before Christopher Herrmann (David Eigenberg) returns from a call not knowing that a small child was hiding inside the truck. Is that because of the reported gunshots near the fire? Or something else? And how did the kid fit in there exactly?
Back in the common room Stella Kidd pulls Foster aside to talk about Severide. She thinks Foster shared “a look” with Severide. Hey, it’s Stella’s irrational jealousy rearing its head again! At least this time she admits that she’s potentially crazy. Foster says she understands, before Casey goes to check the lights in the turnout room and finds the stowaway. The kid won’t say anything, so he gets Brett to keep an eye on him before bringing Boden to see their houseguest.
At this point, Chicago Fire has almost everyone crammed into the turnout room waiting for this kid to say anything. Brett even has Boden take Ambulance 61 out of service to stay with the child. Foster thinks he’s traumatized, while Severide suggests knocking on a few doors to see if they can find anyone who might know anything.

The firefighter from Detroit
Meanwhile, Otis (Yuri Sardarov) finds a man named John Garrett, who says he’s a firefighter from Detroit whose car just broke down outside Firehouse 51. But when Chicago Fire lingers on John looking around the place and then shows us the gun he’s carrying, it’s clear that his story was a total crock. And why is he interested in the lost kid situation?
Casey and Severide’s canvass has turned up nothing, while electricians are on the roof of the firehouse trying to do something, and Ritter (recurring guest star Daniel Kyri) is using Tuesday to get on their visitor’s good side. Because who doesn’t like adorable dogs?
Brett eventually brings the now-asleep kid into the bunk room, where she tells Casey that his random vacation idea is something she’s always wanted to do. She encourages him to go for it. It just sounds to us like Chicago Fire is setting it up for them to go together.
Otis introduces everyone to John, despite telling John that he didn’t see his car outside earlier. When John doesn’t know a fellow firefighter Herrmann mentions in Detroit, and mixes up where he was on the road to, Otis knows he’s up to something and keeps him from leaving by suggesting that he give him a firehouse tour. Personally, we’d let the guy with the gun leave before he shoots somebody, but okay.
Foster checks on the electricians before she and Stella start talking about Severide again. Stella is not happy that Foster told Severide to back off of Stella, saying she doesn’t need the other woman fighting her battles. But she will need her help, because predictably, Chicago Fire has one of the electricians get thrown off the roof.
Almost everyone rallies to help him except Otis, who confronts John about lying his way into the firehouse. John’s response is to pistol-whip him, knocking him out cold, before looking for the kid—who’s woken up and gone missing. An enraged John drags Otis’ unconscious body off, and then enlists himself into the search party.

The truth comes out
Stella decides this would be a good time to talk to Severide, who reminds her that Foster was trying to have her back, not speak for her. And a news report confirms those aforementioned gunshots were from a double homicide. It all makes sense now: the kid saw the murders, and John is the killer back to eliminate a witness.
The entire house mobilizes as Herrmann explains to Boden (and Chicago Fire fans) exactly what really happened. Joe Cruz (Joe Minoso) finds his buddy Otis waking up in the bathroom, while Stella locates the kid—but also John, who holds both of them at gunpoint. Stella shields the child with her body and calls out for help, prompting John to run out of the firehouse.
But he’s not going to get away that easily. Herrmann gives the guy a piece of his mind, before Severide tackles him into the path of a returning Ambulance 61. That allows him to knock the gun away, and everyone piles on to restrain John before Adam Ruzek (Patrick John Flueger) arrives to stuff him into the back of a car.
Ruzek also explains that they know where John’s partner is, and think they can get the two to turn on each other, so the boy—whose name is Logan Miller—won’t even need to testify. Brett goes with Ruzek to return Logan to his parents, while Stella decides that she owes Foster an apology. “Kelly’s my blindspot,” she admits, which sadly is not teasing a crossover with another NBC show.
Stella thanks Foster for having her back, and Foster promises that she’ll always do so. The two share a hug and are immediately chummy again, while Chicago Fire tells us that the injured electrician will be fine and Otis is insisting that he’s fine. Aside from having a bruised ego for not doing his due diligence. He’s angry that someone took advantage of the firehouse’s kindness, but Cruz reminds him that kindness is what brought Logan to their door, too.
Brett watches as Logan is reunited with his family at the 21st District. Casey arrives to pick her up, and so Chicago Fire can give us another Brett and Casey moment. She asks when he’s planning on going on vacation, because she wants to get a group together. And we even get a Carmen Sandiego reference, before the two quietly leave. Was that a hint, show? And was this episode one heck of a trip?
