1. I guess all the queens don't look alike anymore. Pity, I really liked the actress whose played them for the past several seasons.
2. Teyla actually acting like a Queen took Todd by surprise in the end. That was a fun twist. Todd couldn't stop the attack without being revealed as a traitor and Teyla acted exactly like a Queen should act. She actually did a remarkably convincing job of it, although I do wish that she had been the one to kill the other ship captain instead of Todd.
