One thing I hope they don't forget about this season is that there is still a trial hanging over most of SAMCRO, from when they did that raid on the building they thought was the LOAN meeting, but was actually some sort of church function. I mean sure Zobelle is gone, and most of the people in the church probably wouldn't testify without his support, and I think Clay's lawyer said they were trying to get the camera footage thrown out, but even so, pretty much the whole charter, save for Opie, was pretty much caught red handed coming out of a church meeting holding shotguns and automatic weapons.
Yeah, I thought Rosen said that no one wanted to testify and that it was pretty much over (?), but at the very least this would seem to preclude most of them from going to Ireland. (I'm very curious to see how the writers manage that with all those criminal records.)
The idea of Jax's cheating on Tara makes me ill, but I could see back in the season finale when she confessed about her suspension and asked him where they were going that it was too soon for Jax to start being a monogamous family man. They've got some trials ahead of them.
On another topic, regarding Stahl--I bet there will be some kind of alliance between her and SAMCRO at some point, possibly against the Irish. That's such a "Shield" thing, too, making necessary alliances with your most hated enemy. They both have lots to lose and they both know exactly what happened.
