As far as Cassie knew, naturally blue hair came with a mutation and abilities which, while totally awesome, also meant having to be discriminated against for being a mutant. So maybe not that lucky, Cassie wasn't sure. At least they could agree that blue hair was awesome, anyway.
"I tried to dye my hair once to piss off my mom, but it didn't work out well," she said. "It was supposed to be blue but I didn't bleach it first and it kind of turned greenish and gross and I got in trouble at school because they were weirdly strict about hair color and I ended up having to dye it back to blonde," she stopped as the line moved forward a few more feet and she realized she'd been babbling. It was a relief that they seemed to be moving anyway and two customers were served while a third got frustrated and left the line. Good for everyone else.
