Credence is left wounded after the subway battle and taken into custody. But, the real Graves, Newt, and Tina fight to try to help him recover and control his power. He's released to Graves who enlists Newt's help in teaching control or finding a way to separate the Obscurial.

Credence doesn't know how to repay them for their kindness. Cleaning and cooking don't seem to be an issue, so he assumes they'll want sex from him. (Maybe his mother taught him such things happen to wicked boys. Maybe he's not inexperienced with it.) So, he waits for them to act and, when they don't, makes himself available.

Reactions up to author, but bonus points for Tina walking in on Credence in a compromising position and flipping out before anyone can say, "It's not what it looks like!"
