True, but he wasn't really helping Quentin selflessly, his main goal was to save David and find a cure for Chris. At that point in the storyline I don't really think B & Q liked each other all that much, they certainly didn't trust each other at all. I agree about the gravity though.
Helping Jennings and David to the exclusion of all else was, I don't know, myopic.... it puts BC into the role of a cliched hero, who does things because he's "good". I've only just been made aware of the fact that 1897 didn't start intentionally. BC's being trapped, then having to find a purpose in being there, makes dramatic sense to me. He can't return as far as he knows, but even while trapped as a vampire in the past, he can do some good... that I can understand. As long as he's facing the fact that he appears to be trapped. BC rushing around to fix 1969 in 1897, because, well, that's what heroes do, I don't understand, except as a tiring piece of TV melodrama.
