I am really thinking she actually did it, even though I really didn't want her to. Her conversation with Lizzie was very odd. With Rick, I was waiting for her to say they had both already died, or were both already bleeding from their eyes, or something, to further justify. Then they had a such a sweet conversation about the pancakes, then boom, you're gone!
And Bob sure picked the wrong person to tick off! It's been a long time since Daryl has threatened someone. I'm guessing that that incident is not going to put him in a very good mood for the ride back, to find out what Rick did.
Tyreese is just bonkers. I thought after last week, he had snapped out of it, but clearly not.
