Sheppard: Look Teyla, I'm not saying that there's anything wrong with you. God forbid. But you yourself admitted that you were a little off your game. You snapped at Dr Weir this morning in the briefing room for no good reason, and now you're biting my head off for caring that you might need help dealing with the fact that it has been three days since you've had any sleep.
Teyla: I'm sorry, but I do not need any help, the Wraith are coming and what I need is to do something!
Sheppard: Ok, good. I suggest you take a nap.
