As Tommy continues to battle his depression, he and his crew are stunned after Mike's heroic rescue leaves fellow firefighter John Stackhouse clinging to life in the hospital. Still unaware that he was drugged and raped over his relationship with Angie, Tommy apologizes to Sheila. But his problems mount when, after learning that Mike is looking to transfer to another firehouse, Tommy's breakdown at a hockey game exposes him to a police department rival who also suffers from survivor's guilt and has turned to alcohol to cope. Meanwhile, as Jerry ends his brief affair with Rose, and Tommy begs Angie for another chance, Lou decides to get on with his life after the con artist who bankrupted him is arrested. Though tired of constantly fighting in order to keep her interested, Sean asks Maggie to get married. And as Lou tries yoga to start turning his life around, Uncle Teddy's jailhouse wedding is undone by his fight with his bride's jealous - and murderous -- ex-con former husband. Meanwhile, as Franco falls for an attractive artist he met in a bar and Mike is thrown out of the apartment by his gay roommate, Tommy is less than upbeat upon getting the news of Sean and Maggie's wedding plans. Certain he's been given a tip on a sure thing at the racetrack, Jerry persuades his crew to pitch in on a bet that he hopes will help pay for his wife's medical bills. Even though Mike screws up when he's sent to the local OTB office, his mistake ends up picking a big winner that nets Jerry and company fifteen thousand dollars. Finally, as Franco wonders if he's falling in love with Natalie, and Sean is left to make all the plans for his wedding, Tommy persuades Angie to give him another chance. But when Janet shows up at the apartment looking for sex, in the chaos that follows, Tommy ends up losing Angie and getting beaten up by her ex-boyfriend.
