Backlash... Probably jokes about how Cupid should use his powers to make his handler love him so she'll stop being such a jerk. He is up for being flirted with, though it will definitely make him uncomfortable coming from another guy.
whosthere is a super with serial killer enabling abilities who came to GC after killing a handler. He's on Bravo. He's happy to be surface friends with Valentine, but he has strong personal boundaries regarding his personal space and gets stabby when they're not respected. So not too much flirting with him.
gorgonn is still a little mopey right now because she's homesick, but she will probably like Valentine and she is definitely impressed by his wings.
pixieled has been a Ghost since she turned 18, and since they both have wings (hers are butterfly inspired) they have possibly trained together in the past? She is a Foxtrot, but will be transferring to Romeo in the next day... Um, don't quote me on the timeline, because I am wrong at least half of the time! It's happening soon, though.
