i really hope bob and tyreese get bigger roles going forward. big fan of the actors portraying them and tyreese was my favorite character in the books. i hope the writers didn't kill off anyone for the rest of the season. people are expecting someone to die but i would love to see continual growth of the characters we have currently. with that said i think having sasha die (even though shes gorgeous) wouldn't be bad and would add to tyreese. there are a lot of characters right now so developing them all efficiently will be tough. Rick, Carl, Michonne, Daryl, Glenn, Maggie, Beth, Bob, Tyreese, Sasha, Tara, Abe, Eugene, Rosita, Carol, The creepy little girls.
i bolded the people who absolutely wont die by season end. italicized the ones i want to see developed more. everyone else is in my opinion is taking up screen time
