what about when he took all the guns. Can we agree at least that it was crazy and showed his need to control everyone else's behaviour?
Another good character point to expose: somehow--in the daisies and sunshine legal corners of Dale's mind--he thought it wise to hide the groups primary defense....in the middle of a global zombie outbreak. That made him a threat, as his one-sided ideologue schtick--thinking he could make decisions for everyone else
--could have cost the group at any moment.
Whether it was his horny BS about the ever-disinterested Andrea, or playing the last aging hippie protester, Dale had problems.
