Author’s Summary

When Newt rescues a wounded jaguar, little does he know he’s carrying MACUSA’s own Percival Graves along in his case. Trapped in his animagus form, Percival just wants to get home and catch the guy that did this to him. By the time they reach New York, Newt has told his new jaguar familiar any number of secrets, and Percival Graves thinks he might be in love.

Unfortunately for him, Newt’s not going to react well to discovering his familiar’s true identity, and now Percival must find a way to convince him that he’s not just a sneaky bastard, and that dinner at eight really is a great idea.
