I think we're supposed to believe that Blackwater Guy called Tyler for a meeting. Tyler called Jax to ask what to do since they are in cahoots. Jax then set him up with the crazy plan to point to TO and have TO send them to the neo-nazi house. Rat was probably at that bar/clubhouse talking to TO about the plan, but shit went down faster than expected and he got picked up too. It was a very dangerous plan for Tyler and TO (and accidentally Rat) and they could have ended up maimed or dead, so I don't know why they went along with it. I'm sure Jax wasn't worried about the collateral damage, so it makes sense he would come up with such a nutty plan. It does seem out of character for Blackwater Guy to go to the nazi house himself and leave only a guy or maybe two guarding all the prisoners. I think TO might have said the whole charter was at the cabin to get him to take a lot of guys there, but I didn't catch what he said and don't feel like rewatching. The clearing of the nazi compound seemed sloppy too. Maybe Blackwater Guy and team were getting cocky due to so easily capturing multiple Sons and had decided SAMCRO were a bunch of jokers?
That's what I thought too, that he was just acting out due to all the insanity and mayhem in his life. I don't think he was throwing shade at Gemma with the "Do you?" either, as funny as that would be, I think it was just not great acting from a little kid. His actions this week are much more awesome if you ascribe them to adult motivations, but I think that's the same as thinking your dog dug in the trash because he was mad at you. Dogs are not that complex, he dug in the trash because it smelled delicious, not because you yelled at him earlier in the day. Although, the fork might have been his weapon of choice due to overhearing that's what killed Tara. Are we supposed to think Thomas really scratched him, or was it another instance of self-harming and he just blamed Thomas? I do think 5 is a little young to be a cutter, though, but I guess Abel has had a pretty shitty, chaotic, and violent life.
