Sock: Real or An Alien? Edit
Sock is the name of a character who turns out to be Wilfre--but what if the Sock we see wasn't really Wilfre at all? What if... the "real" sock was "real"ly an alien.
At some point in the game, Sock mentions aliens.
Sock disappears and is not seen after the pendant scene. Where did he go?
It is possible Sock may have been a real person who Wilfre was intending to take the form of in order to get the Pendant. Jowee would have trusted Sock with the Pendant so if Wilfre asked for it as Sock he'd have been given it.
