Plot
Feeling The Ogre may be coming for Lee (Morena Baccarin), Gordon (Ben McKenzie) unsuccessfully tries to convince her to leave town. In a bar, Lennon (Milo Ventimiglia) has a new date: Barbara (Erin Richards). He plans to kill her in her penthouse but decides not to after he realizes she feels lonely and depressed. Not comfortable with him, she tells him to go.

Gordon and Bullock (Donal Logue) interrogate the first victim of The Ogre's revenge, Detective Ben Mueller (Laurence Mason), whose wife was killed by The Ogre. They're then cornered by The Ogre, who then calls Gordon and threatens to kill someone unless he retires from the investigation. While inspecting a manor, they save a butler, Jacob Skolimski (Daniel Davis) from being hanged and discover the corpse of Constance Van Groot. They realize the Ogre is called Jason Skolimski, the son of Jacob and Constance Van Groot (the foster mother), who killed her for not being a good mother.

Bruce (David Mazouz) and Selina (Camren Bicondova) continue their investigation in Wayne Enterprises. Accompanied by Barbara, they attend Wayne Enterprises' Charity Ball. While Bruce distracts Sid Bunderslaw (Michael Potts), the director of Physical Operations, Selina steals Bunderslaw's keys to make a copy. Cobblepot (Robin Lord Taylor) is forced to have dinner with Maroni (David Zayas) and his mother Gertrude (Carol Kane). While talking, Maroni reveals to Gertrude that his son has killed many people. Cobblepot swears to kill him.

Critical reviews
"Under the Knife" received positive reviews. The episode received a rating of 77% with an average score of 6.7 out of 10 on the review aggregator Rotten Tomatoes, with the site's consensus stating: "Gotham finds the right mix of creepy and fun, even when the plot of 'Under the Knife' spreads the characters a bit too thin."

Matt Fowler of IGN gave the episode a "good" 7.3 out of 10 and wrote in his verdict, "With no Fish to follow (yay!) Gotham actually figured out a way to insert Barbara back into the story in an intriguing way. She could have just been a victim of the Ogre. Or someone that Gordon needed to save (again). But they chose to make her somewhat of a broken kindred spirit. Does she know what she's getting herself into? Probably not. But it'd be even cooler if she did."

The A.V. Club's Kyle Fowle gave the episode a "C" grade and wrote, "Now, through two episodes post-break, and with only two more to go, Gotham appears to be falling back into the pattern that’s defined most of this season, which involves convoluted storylines that stretch the characters (and audience’s patience) thin and rely far too much on exposition to move the plot along."
