Hey Lesley, welcome to the game! It's Zoe (oceanic, we were in Willowbrook together!!), it's nice to run into you again! :)
I'll copy Angie and link you to my intro! I definitely have Grace to throw at you, though: she's the B52's medic, from Venus, and also comes from a Korean family. I don't know if he speaks the language or not, but if he does, she might chat with him sometime in Korean just to keep her language skills intact when she's not at home. (Her name is Eun-Hye but she goes by Grace to anyone who isn't family, really.) She's also kind of reserved and polite, but she also has a maternal streak and would look out for him, since she generally does that for the other medics anyway and he would probably get her soft spot spot for being such a baby. :')
