Plot
As part of their plan to get his mother back, Butch tells Theo Galavan that Cobblepot cut off his hand for thinking he betrayed him and offers to work for Galavan. Galavan initially declines, stating that his associates "have both hands". Tabitha agrees to let him join them but Barbara is skeptical, citing when Butch kidnapped her. Finally, Galavan lets Butch be part of his operation. Galavan also threatens to kill a congressman if he doesn't support him in the elections, which ends when the congressman agrees to his terms and his life is spared.

Meanwhile, the strike force, led by Gordon, catch a thug and accuse him of being the arsonist who killed Officer Garrett in the previous episode. Bridgit is having a rough time after having killed the police officer. She lives with Selina, but continues to feel guilty. Selina proposes to get money so she can leave Gotham City and both of them steal money from a human trafficking slave-ring. During their escape, they're caught on camera, and Gordon recognizes Selina. On their way to the bus station, Bridgit is kidnapped by the Pike brothers. Selina plans on rescuing her but is found by Gordon. Selina gives the information to Gordon, but Gordon states he will take care of the situation.

Bridgit is brought back to the Pike home where her brothers taunt her fear of fire by threatening her with firecrackers. Tired of their abuse, Bridgit kills them with a flamethrower. While looking for the whereabouts of Cobblepot's mother, Butch is discovered by Galavan and learns that he knows of his and Penguin's ruse. Galavan figures out that Oswald has a mental hold on Butch and tells Tabitha to try to beat it out of him. Selina reunites with Bridgit but realizes she's changed in her attitude and plans on taking down abusive people. Bridgit returns to the slave-ring where she burns the captors and frees the women.

With a tip from Selina, Gordon, Barnes and the GCPD arrive at the slave-ring. Gordon tries to calm Bridgit, but she fights back. However, she accidentally catches fire while trying to defend herself. In an attempt to co-opt Bruce, Galavan proposes to help clean up the corruption in Wayne Enterprises. Butch escapes from the Galavans and tells Cobblepot his mother's whereabouts. Selina appears at Leslie and Gordon's apartment and is heartbroken when Gordon tells her Bridgit won't survive her injuries.

Nygma reveals to Kringle during a visit that he accidentally killed her ex-boyfriend, Dougherty. When she tries to leave and tell someone, he holds her and tries to keep her from screaming, but he unknowingly strangles her and she dies in his arms, leaving him shouting and crying in grief.

In an underground facility of a division of Wayne Enterprises, Bridgit, still alive, is brought to Indian Hill labs where scientists experiment on human beings.

Critical reception
"Rise of the Villains: By Fire" received positive reviews from critics. The episode received a rating of 79% with an average score of 6.5 out of 10 on the review aggregator Rotten Tomatoes, with the site's consensus stating: "Though season two continues to struggle with tonal consistency, 'By Fire' sets up a fun showdown between some of Gotham's most explosive characters."

Matt Fowler of IGN gave the episode a "good" 7.4 out of 10 and wrote in his verdict: "'By Fire' may have been another one of this show's villain-as-a-kid origin tales, but it was utilized nicely right at the end to open up a whole new side of the series - that of the Indian Hill monster farm."

The A.V. Club's Kyle Fowle gave the episode a "C" grade and wrote, "The biggest problem plaguing 'By Fire,' and really Gotham as a whole, is that it wants to explore the story of Gordon’s potentially compromised morality with as much gravitas as possible while also insisting that the more comic and cartoonish tendencies are fine because hey, this is just a comic book show, right? It’s a flippancy that’s insulting to anyone who watches the show and tries to invest in these characters, and it’s a general lack of attention paid to storytelling that results in frustrating swings in tone."
