Cat and Tess head out for a night of fun. Cat wants to forget about Vincent, who is also stressing now that his memories are starting to come back. He tells Chandler that he needs another Beast so he can keep busy and not think about Cat. Fortunately for him, there's a serial arsonist that Gabe determines to be a fire-resistant Beast.
Cat's night out doesn't go so well as she ends up in a fight (although it's pretty one-sided when her opponents are loud-mouthed drunks). She ends up getting arrested after one of the people she punches ends up being a judge. Gabe bails her out and scolds her like a child before filling her in on the fire-resistant Beast. He wants Vincent to help catch him, not kill him, to try to undo the his Beastly condition in the same way they undid his own. If they can re-create the results on the arsonists, they could cure Vincent. Cat wants no part of this investigation or plan, seeing as how arson isn't even under their jurisdiction.
Gabe pays a visit to Vincent's boat, risking personal safety to put him on the trail of the arsonist as well as tell him a bit about their history and dangle the possibility of his becoming human before him. Vincent heads out, determined to kill it. He uses his Beastly abilities to track the arsonist down to his latest fire. It's there that he learns that this Beast, Eddie Long, is not only fire-resistant but a fire-starter as well. Eddie unleashes some flames on Vincent, kicks him while he's down, and walks off victorious.
Cat is at a spa with Tess and is repeatedly getting distracted by talking about Gabe's plan. Gabe calls to interrupt the session, but she doesn't answer. He tries calling Tess and then the spa, forcing the womyn to cut short their pampering session.
Vincent is rescued from the fire by some firefighters and Gabe has managed to get Vincent hidden in a hospital room to hopefully keep anyone from ID-ing him. Vincent shares a private moment with Cat in which he tells her he wants to finish his mission so he can be with her. Meanwhile, Chandler has arrived at the hospital in search of Vincent, knowing that "John Doe" is really him. He spots Gabe with the arson investigators, who want to interview Vincent. Gabe tells them that Vincent is named Victor and is working undercover for the DA's office. As it turns out, the younger of the investigators is Aaron Keller. When his name is mentioned, Vincent's heart begins to race as memories come flooding back. Gabe orders the arson investigators out as Cat struggles to get Vincent under control. Vincent is remembering that Aaron is his nephew, the son of Vincent's dead brother William. Overwhelmed by the memories and unable to get his heart rate under control, Vincent beasts out and leaps through the hospital window.
Vincent calls Chandler, who says that he just has a few more missions and then he'll be done. He tells Vincent some background information on Eddie being a convicted arsonist that Muirfield ran experiments on, advises him to stay calm, and to steer clear of things that will trigger memories. Vincent returns to his boat to find Cat waiting for him, wanting to be sure that he's okay. He opens up about Aaron, William, and the memories that came back of the day William died.
The team figures out that all the building are owned by a wealthy oil executive. It's not long before another one of those buildings is set on fire and the firefighters head out, realising that Aaron has run off early to try to take the arsonist out himself. At the fire, Cat tries to stop Vincent but he kisses her and tells her not to worry.
Aaron comes face-to-face with Eddie, who takes him out with a small explosive device. Vincent gets in and prepares to face off with Eddie once again. Eddie attempts to use his running fire trick but Vincent has learned from his mistakes and claws a water pipe to put out the fire and begin fighting him properly. Aaron's firefighter alarm goes off and while Vincent is distracted, Eddie runs off. Vincent struggles with flashbacks of William telling him he needs to go back to medical school since their mother couldn't handle having another son as a firefighter, and then him losing his brother in the twin towers. A vision of William guides him to Aaron, and he scoops him up to get him to safety.
Cat and Gabe encounter Eddie, and Cat has to shoot him to prevent him from attacking and/or escaping. They try to use the defibrillator but they're not able to resuscitate him. Vincent gets Aaron out and whistles the firefighters over to look after Aaron. Later, Aaron pays a visit to Cat at the station to thank her. She warns him to be more careful from now on. He asks to talk to her partner (Vincent) to thank him for saving him but he won't be able to do that in person since he's "undercover."
Cat and Vincent go for a walk. He's adjusting as best as he can to the memories coming back but he's also happy to have more of who he is. They pay a visit to the memorial site of the Twin Towers and pay their respects to Vincent's brothers. Vincent wonders if he could have saved them if he had stayed in his profession as a firefighter and Cat advises him not to think about what could have been. They hold hands and prepare for what's to come, any of which they will face together.
Beauty and the Beast airs on Mondays on the CW at 8PM.
