Hmm... I always thought it was likely that Bao-Dur was originally going to die, whether it was at Malachor V or at M4-78. It just seemed to be heading that way until half way through the game-which is when there is nothing more to say to the guy...
I don't mind his voice so much, but the volume and quality is terrible at times. Seriously, I thought he was whispering or something before I turned up the volume and realised... wow, they didn't work too hard on that voice did they?
