When I think of B, I think of a lot of ambiguity. I don't feel like I know him as well as the series canon characters, I feel like he's deliberately shrouded in a lot of mystery that leaves room for interpretation. But he is peculiar and hard to understand. He doesn't express a lot of personality that's easy to relate to, he's quite accurately described as abnormal.

B killed the people who were going to die anyway, apparently. But I can't help but wonder if their cause of death was "serial killer" - as in, their cause of death was B himself. Their lifespans could have been approaching zero because of him. Though, the idea of fate and a lifespan is always confusing to me, mainly because predestination is so incredibly tricky. It seems to me that if someone knows an outcome, they can certainly change it. B very likely justifies himself as the "angel of death" who serves the inevitable, but perhaps he himself is that fate.

What would B be like without L? I think L was someone he latched on to - it could be for a lot of reasons. Ambition, competitiveness, admiration. If L had never been around, perhaps B would've latched on to someone or something else. Or if no one else was there... who knows. He might go either way.

B is a really interesting character, suffice to say. Good read, makes me think. :-)
