So Percival is found but he's trapped in some sort of time loop curse and no one knows how to free him. Deciding to try their best the attempt and break the curse but as a result Percival is aged down. The boy latches into Newt who takes care of him and as he ages up Percival developed feelings for the man. This can be cute and platonic or something more as Percy grows up, up to you.

Cute Newt boy Percival interactions please!
