OKAY ONE OF MY DEATH PREDICTIONS IS RIGHT THUS FAR!
I'm not sure how she survived so long, she did not, in my opinion, possess the characteristics of a survivor (as the rest of the group did.) Moreover, it was a good arc to come to an end, I feel storyline focus should shift elsewhere with some undeveloped characters, i.e: Abraham (and practically all of his group), Tara, and even though we know so much about Rick - he is certainly undergoing a transformation from sane, calm consciousnesses to bloodhungry and impatient.
Rick and Daryl seem to almost have switched personalities in terms of rationalizing situations.
