This was an excellent episode!

I loved analogy of the twilight bark, and when no one knew what it was-- he mentioned Lord of the Rings, and how everyone was nodding because they knew what he was talking about.

I feel that they were right to suspect Kavanaugh, but Weir really did cross the line when she let Ronon go into that room with the intent of interrogating him. Big surprise on Caldwell being the Goa'uld!

I loved the Circle Ceremony and Teyla's singing! It gave a glimpse into her culture, and I always like that!
