Keep killin' him. Eventually, he's gotta stop comin' back, right?

[ But that doesn't seem like a very viable plan and Rick knows it. He sighs, long and suffering. ]

We'll find a way. A guy like that has to have some weakness -- some point we can get at him. If nothin' else, breaking his hands and cuttin' out his tongue would keep him from bein' able to talk to anyone or do anything. Just hope no healer would take pity on him.
