Yeah, that does appear to be our best bet as far as Voq goes. I'm kind of also hoping he might integrate Ash's memories and realize that hey, Humans aren't so bad, this one seems nice, and that one over there, too, and that one... but, then again, Ash has about a bazillion reasons to hate Klingons, so that might not work out so well.
