Not the greatest episode, but not bad either. Nice to see Tara out of jail and secretly planning to divorce Jax. Adds some much needed tension and makes her somewhat more interesting. Also, the cop whose sister was killed is crazy as fuck, just what this season needed. Hope he really shakes things up and doesn't serve as device to merely move the plot forward.
Not sure I'm happy about the direction the school shooting story is going, seems to be something Sutter thought would be shocking (and it was) but he lacks the chops to turn into something interesting and impacting long term. Hope I'm wrong, but his past failures in exploiting tragic events tells me otherwise.
