At the end of the episode when Sheppard asks Larrin if she was going to stick around, she said she had things to take care of. She also said to Sheppard that it was "nothing for you to concern your pretty little head with."
What does Larrin have to take care of?
Attacking Wraith ships?
Taking control over the entire Traveler race?
Any other ideas?
Rumor is that...
