Oh my gosh, I'm absolutely stoked for this!! I not only get to be Bandit's best, and only, friend, but Ray's girlfriend! This story is already amazing, I can't wait for more!
OH! Annnnd... why don't just use Ray's kill joy name? If not, then how about:
1.) Dim Dexter (Kind of an oxymoron, also based off Dexter's laboratory)
2.) Trenchant Hooligan (IDK about this one, seems kind of long and odd)
Thanks, and happy writing! :)
