I couldn't honestly give a rat's ass about Cole. Saw his reviews, they're unbelievably boring. Also, he gave Toy Story 3 a bad score? Was he huffing a small paper bag containing Chris' DIRTY, CRAPPED BRIEFS before he sat down to watch it or something?
Either way, though, him finding out who his father is will probably never happen. The trolls figured it out long before he did, mind you, but I'm guessing what he really wants is closure from Barb.
...yeah, good luck with that. Should've bought that Poke Flute.
