I'm pissed that they got rid of Tyreece so quickly. He's a really cool character in the comics and should have been heavily involved by now. And the whole "Rick is crazy" feels like a way to fill episodes and simultaneously ruin the characters in the process.
I loved the Talking Dead episode afterwards, though. "Why can't Carol have nice things?"
And I have no idea who the chick driving the zombie bomb was, but I am sure it was a woman.
