The successful destruction of a starship belonging to the long invincible Ori was the most satisfying and cathartic experience yet since the Ori made their first appearance. I only wish they had shown a shot of the Ori on the bridge just as their starship was being destroyed.
The "backwash" that occurs during the initalization of a Stargate is dangerous. It disintegrates anything in its path. Just how dangerous was underscored in an earlier episode, when a Stargate was used in a funeral ceremony. The body of the deceased was laid on wooden scaffolding positioned in front of the Stargate. The Stargate was initialized and the backwash "cremated" the body and even the upper portion of the scaffolding.
Teal'c ingeniously uses the Ori's own Supergate to annihilate an attacking Ori starghip. Teal'c uncharacteristically uses his brain instead of his brawn. He uses technology to solve a problem instead of muscle. He does rocket scientist Sam Carter proud.
