To emotion OCs, because those are all the RAGE (slow clap for my humor). Brother and sister, since they're both symbolized by the color red. The boy is Rage, the girl is Lust. Both single, because that's what we're all wondering, though that changes for List on a day to day basis... And no, this is not an insult to females. I am a female. I don't tend to insult myself (much). Rage just seems more male, so balance.
