I know Sarevok has an alternate, evil ending for Ascension if you fail to redeem him, and I'm interested in seeing it. Question is, I know there's a chance he will betray you in the final fight so I was wondering if it was possible to keep him evil and retain his services (I suspect the oath may come into play here but I don't normally make him swear it).
Cheers for help.

I'm pretty sure that Sarevok will betray you in the final fight if you don't redeem him. If there's a way to not redeem him and keep him with you, I've not found it (and don't know anyone who has).

OK cheers. Guess I'll be redeeming him again then eh!
