I just rewatched the episode and something doesn't add up. Where did the darts came from? In Stargate Atlantis, Wraith cruisers don't have fighterbays where darts can land, only hiveships can. So unless the darts came from the space gate orbiting the planet, where did they come from? If they did came from the space gate, how come the wraith cruiser got there earlier than the darts did?
Unless two different factions have send them, even though they are at war with the Asurans and those factions have formed one unity against a common enemy.
