i'm not sure what i could throw kang out for, but i will anyway! he's former alliance military-turned-terminus medical doctor with a family that is pretty interwoven into the alliance healthcare system on babylon (whereas his sister, ~sheolyun, worked with weapon/defense tech for a while). i can imagine them not seeing eye to eye since kang's moral compass points north in a neutral way (as in he'll treat anyone that comes into the clinic, good or bad or morally grey as they may be).
