I can tweak it so his mature side reasserts it's self if you like? And sure... go wild.
I don't even mind if he gets physically regressed. Hence the hints of other methods.
I'm easy on whoever... depends on who you wanna play?
Idly I also have an odd desire for a Grodd and his Grandson RP sometime.
Like Sam trying to use his psychic powers to convince Grodd he's baby. But Grodd manages to shrug it off and deviously decides to use is tech to make Sam (his Grandson) an actual baby. I dunno… just an odd thought.
