I noticed the shabbiness in this episode particularly. Rick always looks greasy and grimy but I thought when I watched this episode that Morgan was wearing a shirt that was badly frayed at the collar. In that town there must have been some clothing stores and it would not take much to have decent clothing. Rick should be wearing his uniform or something reminiscent of it so he projects authority instead of looking like a slime-ball. I know the Walkers would not take any clothing so there must be all sorts available. I think if I were there I would change my clothes every few days just to feel good. Also why doesn't anyone take bathe when there are streams and rivers aplenty?
