Has anyone thought of who could be Finn’s younger sibling yet?
Because I’ve thought about maybe it could be Susan Strong, I mean, she does look older than Finn, but then again she could just be mutated into being more muscular and all that.
Also Susan does seem to have more of a childish mind, and learns very quickly. Maybe she could technically be younger than him.
Isn’t Finn named Penn in the first episode? Maybe Penn is farm Finn and Finn is the younger sibling?
