(LEXA WAS AMAZING OKAY?!) Crazy makeup is more of Harley's thing. He likes to do his hair pink and blue too but he can never deal with the upkeep. Not exactly a lot of hair dye around these days.
It would be fucking amazing to have Nick around. There's so much potential for him, on the show and in game, and it's just so disappointing when he fucks up. But the, that's the character and I love that he's like that at the same time. So Harley will sign up to fill that void in her life. Not intentionally, of course but because she's so young (jesus, Negan, she just barely hit drinking age), he'll be instantly protective of her without realizing it or meaning to. He's still very much of an asshole but he'll be less so around her ;3
