I've never seen Stargate Atlantis, but now I can only assume that that's the physicist and the doctor by process of elimination, which a Google search leads me to believe is Samantha Carter and somebody because I only saw one physicist but about 10 "doctors" of various stripes in the character list.

I'm quite proud of myself for guessing fandoms purely on language! There was just something about the words you chose that suggested the fandoms to me. I know nothing about them, couldn't name you a character out of either fandom, but I got something right!
