I just finished the game, and reran the end sequence several times, and tried different conversational paths with Kreia. No matter what I do, I seem to end up wandering off in search of Revan, which, it appears, is a "Dark Side" ending? At least, that's what the Game center Achievment declared. I expected tthe ending to involve re-trashing Malachor V with the "Shadow Mass" thingie, but that never comes up as an option. My character is so lightside-aligned it hurts my eyes to look at him, but I seem to have no control over the ending. Am I missing something? Thanks, if anyone can clear this up.
