Teyla: You are a doctor, right? Heightmeyer: Psychologist, actually. Teyla: And that is...different than Doctor Beckett? Heightmeyer: Quite, yes. Um, I deal with the mind. I try and help people deal with emotional problems like anxiety, depression, post-traumatic distress. Well, needless to say I've been pretty busy since we got here. Teyla: I can imagine. Heightmeyer: I'm sure that you do a lot of the same things that I do for your people. But it must be very hard on you, always having to keep such a brave face. Teyla: From strength comes hope. Without hope, my people would be lost.
