Carter: Major Dorsey and his team just returned from M6R-214. They examined the debris field above the planet and found the parts from one, possibly two, Replicator ships.

Sheppard: The Replicators may look like the Ancients and they may use the same technology but they're gonna be a lot tougher to put down.
