Matt and Trey could tie the Kenny is reborn plot in. Perhaps Kenny's parents made a deal with the Chutulu, that everytime he dies his soul returns to his mother, she gives birth to a new baby with a parka, she puts it to bed and it grows up overnight. And everyone remembers him dying, they just don't care as they know he will always come back.
Well, this is only speculation, but there's a distinct possibility that part 3 could involve...
Chef's parents, who have been involved in Kenny-related spirituality before, and perhaps we could even see an appearance from Darth Chef, which would be one of the last "loose ends" they could possibly tie up. The Cthulhu cult members were meeting in "Jim McElroy's house" -- Chef's real name was revealed as Jerome McElroy in "Chef Aid", so I doubt that's a coincidence.
