Good grief. Character development? Wait until she's of age? Darryl has issues...who doesn't? Sounds like y'all are watching a freakin' Hallmark movie.
How about Darryl swaps jailbait to roving band of survivors for some M-14s and a couple cases of ammo, after he's satisfied his baser urges with her, and then he's off on his merry way to slaughter some zombies, and find his next adventure.....not reflect on his past, his feelings or some other such nonsense.
That is such a Ricktatorship thing to say.
