OKAY SO WE TALKED ABOUT LEA AND DAE BEING CHILDHOOD FRIENDS.
lea probably beat him up once as a kid for some reason, and then they became friends. when he left for training she was like take me with you!! but she was too young, she probably ends up in the med bay fairly often for minor injuries bc she's reckless and has low self-preservation skills. she's not good at academics so everything he does is a mystery to her, she's always simultaneously bored and in awe.
lux was in his graduating year! she's also very reserved but more like quietly pessimistic. she's an engineer but since he seemed more mature they could have been friends or at least friendly? she's on the b52 & from europa.
cody is a puppy!! they would have had one overlapping training year, he graduated in '68. he's a pilot and he's very friendly so if they ever crossed paths he was very enthusiastic and very nice! he's not good with medical stuff but if he wanted to train in anything else cody would have offered to help!
