Halloween
"Kind, sober and fully dressed." Good news, everyone. We found the name of Santiago's sex tape!
She didn't know why she agreed to help him. She hated Halloween, it was her least favourite night of the year. They had easily double the work on that October night, and yet Jake was making silly bets with the captain. He thought he'd win, Holt knew he couldn't win, and she still wanted to find out what would happen.
Peralta, despite being a pain in her ass, was a good detective, and his plans occasionally worked. And since Holt had met the Vulture, they were working better as a team. She kind of wanted to prove to Holt that they could work together as a team.
Maybe she didn't hate Halloween as much as she claimed she did.
