Put up a little poll. This is for fun. Merle has made an enemy of nearly everyone on the show. Right now...I think only Daryl has the slightest possibility of sticking with his brother. But what do you think?
My "death of Merle" story would have him at the prison running from Walker and runs into a closed cell door. He fumbles for the key with his good hand...it slips out and he can't catch it with his "bad" hand and it falls either in a grate or bounces out of reach on the other side of the door. Last words, "Well that just figures."
