This may be a bit much, but can I add in Daryls brother Merle? He is an asshole and will get himself into trouble, straight after (or even before) getting Elizabeth he'd get violent and be left behind... If you know where I'm getting at.
Actually before we get to Elizabeth.
So basically he does whatever, Daryl is the main one but Merle tags along. Merle gets himself into trouble and is left behind, they find Elizabeth and Daryl clings to her as she is the only one who didn't aid in having his brother left behind.
If you've seen season one of TWD you'd understand. But I can assure you, Merle is like an NPC who will be gone very soon.
