I believe that Soren will come back in episode 8. If you want to know the reason why I

believe this, it's because of the small hints I caught in the last two episodes. Episode 5 had

the founder's throne room, and had that large bookcase. If you walked over to it, there'd

be a book by Soren. In episode 6 when you go to the white pumpkin's lair, there's also a

Book by Soren there! In all these other dimensions, Soren's books have appeared, which

not only makes me believe that Soren will come back, but it also makes me believe that he

was one of the old builders! It makes sense... perhaps he's from a different dimension,

building portals to help him escape, and leaving behind a book of his discoveries... or I

might just be insane... who knows?
