Who is "Sasha"? That lady with Tyreese? Is she his sister or love interest? I never really got that.
This is the part I liked: In addition, Melissa Ponzio, who appeared in four episodes of the series this year as Karen, will return for Season 4 as a recurring character.
She is really, really cute IMO. She could fill in well for Andrea.
I like her as well - and unless I'm mistaken, she had a role in the comic at the end of the prison battle and pulled the trigger on a certain character. Could be a different chick, but I think it's supposed to be the same one as Lilly Caul from the comics, just with a different name.
