LOL, if Billy steals Hershel's daughter it would definately set-up a portion of the Billy/Carl story from the comics I was referencing earlier. Also, if they kill Tyreese in the show, I am going to be pissed right off, I had to deal with his apparent death, and actual death in the comics already, I can deal with my favorite character dying again.
So really, all that matters is that Tyreese is finally here, ITS HAMMER TIME!
