The real Percival Graves wakes up in a strange workshop, haivng been released from the tiny cigarrette case he'd been imprisoned in, to find that his rescuer is none other than his old friend Theseus' little brother.
Unfortunately: Percival doesn't have his wand, they are on a No-Maj boat in the middle of the ocean, and apparently Theseus used to steal his little brother's stuff (including playmates) so often that Newt has decided to return the favour.
