Now that he's a kid, he can use the magic of the potion to help him understand what's going on around him. He doesn't know if he'll be able to figure it out physically or mentally, but he does know that the potion can either make him physically and mentally "a kid" or "a guilty turn-of-guilty ignore" . He wonders if it's possible to make a person "both physically" and "mentally" a kid. He's not sure whether he can figure out that either way. He also wonders if the potion will help him to "defeat the willies" and destroy the world.
