Billy (spoilers)

I recently got hooked on this show in spite of some puzzling details.
Like Billy roughing up that barrister from the Oxford trial to make Clive's problem go away. I guess Billy decided he had nothing to lose since he was dying anyway. But how could he really have got away with it? That barrister doesn't seem the type to let it go, unless he was truly frightened for his life.

Even before that, Billy seems like a thug, but for some reason I still liked him. He expressed his respect, admiration, and love for Martha and Clive openly.

But then there was the sexual harassment case. That was ugh. I don't know how Martha could excuse his behavior even if he was dying. What he did was downright creepy.
