When Ford captures the team, he behaves like he has no idea who Ronon is, he even asks, "Where did you find this one, Sheppard?" Ford met Ronon before Sheppard did in Runner (2005).
When Sheppard is sitting in the wraith dart waiting for the mission to start, McKay is standing on a ladder that is hooked over the side. When the shot changes angle to the outside of the dart, the ladder is gone and Ford climbs up. Then it switches back to the inside view again and the ladder is back.
When Sheppard throws a flash bang grenade at a Wraith drone while on the hive ship, the actor playing the drone reacts prematurely to the effect.
At about 15 minutes, in the Genii lab taken over by Ford and his group, two Philco Predicta television sets could be seen used as computer monitors. The word PHILCO could be seen on one of the sets and also the word PREDICTA could be seen on the CRT bezel of another. Genii do not use English wording on any of their other items.
When McKay was frantically dialing out on the DHD, a crew member or actor could be seen hiding behind it.
