Santiago has more in common with Peralta than she thinks. She doesn't make up undercover characters when none are called for, but if the situation does call for a character she can be nearly as ridiculous as Peralta is, and she riffs off of him incredibly well. Nobody jumps into roleplaying with Peralta was quickly and easily as Santiago does, not even Boyle, who tends to just repeat whatever Peralta is doing. We first saw her do it in The Bet, "No, I know we're lost. I think he's an idiot!" and then again in Charges & Specs. "I heard a pop! I heard a pop! Is that bad? OH, I LIVE TO DANCE!"
