'Chicago Fire' Season 9 Episode 2 Review: Is Brettsey going ahead full steam or has it sunk already?

Spoilers for 'Chicago Fire' Season 9 Episode 2
'Chicago Fire' is back with a new episode that continues from the Season 9 premiere when paramedics Sylvie Brett (Kara Killmer) and Gianna Mackey (Adriyan Rae) in Ambulance 61 were driven off a bridge when the addict from last week shot at them. Thankfully, both of them make it out of the ambulance -- making Captain Matthew Casey's (Jesse Spencer) heroic jump from a moving firetruck to get to them absolutely pointless. They see that the man who shot at them also crashed and rush to get him out of the overturned car which is on fire. However, things are going wrong at every turn, yet Brett manages to pull him out of the car.
Firefighter candidate Blake Gallo (Alberto Rosende) checks on Mackey and asks if she is okay. Both Mackey and Brett say they are fine and don't need to go to the hospital, but it is clear that Mackey is really shaken up. When they get back to Firehouse 51, everyone is concerned -- but none more so than Joe Cruz (Joe Minoso) who hovers over Mackey, surprising both Gallo and Darren Ritter (Daniel Kyri), who haven't seen him so overprotective.
Meanwhile, Casey goes to speak to Brett -- who is told to decompress along with Mackey until they get a replacement ambulance --, who tells him it was weird seeing him as soon as she got out of the crashed ambulance and asks him how he got there so fast. She remarks, "It's always you," to a bewildered Casey and then says how he is always there for her. But she quickly backtracks making us wonder whether she is friend-zoning him. However, Brett later tells her friend that she is worried about things changing with Casey -- when Brett and Casey talk in the locker room later, things get really awkward.
At the firehouse, with Chief Wallace Boden (Eamonn Walker) getting frustrated with the paperwork to get the new ambulance, Ritter and Gallo volunteer to help him, leading others to pile them with clerical work. While Ritter does not mind, Christopher Hermann (David Eigenberg) and Randall "Mouch" McHolland (Christian Stolte) remark about how they never took part in clerical work.
We also see that Stella Kidd's (Miranda Rae Mayo) Girls on Fire program has restarted and her boyfriend, Lieutenant Kelly Severide (Taylor Severide) is helping her with the preparation. Boden is proud of the way Kidd is moving ahead, but Kidd is concerned because one of her best students has not shown up for the classes. She later tracks the girl down and talks to her, with the latter telling Kidd that the recession due to Covid-19 has put her family on hard times, so she doesn't get time because she is doing part-time work. However, Kidd sees the guys being overwhelmed with the clerical work and gets the girl an offer to work at the firehouse.
Later, Cruz checks up on Mackey and while she is okay, she feels she may not be cut out for the work at Firehouse 51. However, Cruz -- who made a promise to Mackey's older brother who is deceased to protect her -- reminds her that she is doing well and that her brother would have been proud of her.
At Molly's later, Cruz and Brett talk about Mackey and they are concerned that she will leave, but Ritter reassures Cruz that Mackey will be okay. When Brett joins a table of firefighters, things are still awkward between her and Casey, but get even more so as Gallo tells the story of Casey's heroic leap earlier. Brett then abruptly leaves.
Meanwhile, Severide is on a mission to track the crashed ambulance because he wants to get something from it. It takes a while and Severide also has to sneak in the yard, but he manages to get to the ambulance. It turns out he wanted to take the ambulance door which had Leslie Shay's (Lauren German) name on it. He fixes it on the new ambulance with Casey's help and tells Mackey -- who has decided to stay -- that he did this so that the people who come to Firehouse 51 will remember whose shadow they are walking in.
Later, as Ritter, Hermann, and Mouch drive back to the firehouse, they see people calling for help from the subway platform. Ritter rushes to the platform and jumps on it to see a person collapsed on the track. He heroically (and quickly) gets the person off the track, before being pulled out just in the nick of time with Hermann's help. While everyone is admiring Ritter, Mouch (his mentor), talks to Ritter about the latter's willingness to help with anything without expecting anything in return.
Once the shift is over, Casey makes it over to Brett's house and asks why she is avoiding him. He wonders if he did something wrong and instead of explaining, Brett kisses him and they end up spending the night together -- giving Brettsey fans what they have been waiting on for nearly two years. We don't know though, now that it is finally here, we feel uncomfortable with the pairing. When Brett asks if Gabby Dawson (Monica Raymund) returned, would Casey leave and the latter says he hasn't talked to her in a long time. Casey being unsure of the answer is enough, however, to put a stop to all things and the Brettsey ship has sunk as soon as it has sailed.
'Chicago Fire' airs on NBC on Wednesday nights at 9/8c. 'Chicago Fire' will return with new episodes on Wednesday, January 6, 2021.
