Bobby is just pissed from Jax going behind the clubs back basically to get rid of Clay (with planting the gun, etc.). Once they get 4 members to patch out they will be Nomads so Redwood will more than likely lose a member here soon.

Not sure why Juice looked uptight yet. It was hard to tell by reading his and Jax's face what the true plan was after he injected the chick. I still think Jax was in on the smothering, but the way Juice acted afterwards makes me think that wasn't the plan, or he was just that uncomfortable with doing it.
