Random crazy speculation/prediction. No preview spoilers, just a thought after the episode.
I kind of think the Otto thing may become the final turning point for Tara. With her not telling Jax I get the impression that she will go through with his demands, but I think he still won't recant his statement. Which will lead Tara to go crazy, but she still can't tell Jax so she kills Otto somehow. Ties up the loose ends and sends Tara into a crazy new direction.
So far this season makes it seem like Tara is on edge, but I can't really see it headed anywhere new on it's own. It would also not make much sense to ignore the logic that Tara wouldn't be allowed to see Otto unless there was some other point to it than to just drop his statement.
I'm probably way off, but I was just thinking there has to be more coming from the Otto/Tara scene.
