During this episode, the ship that Doctors Carter and Jackson fly on is a time-traveling version of the Jumpers from Stargate: Atlantis (2004). When the Atlantis expedition first discovered the Jumpers, Doctor McKay and Lt. Aiden Ford tried to name them Gateship 1, 2, etc. However, Sheppard did not like the name and renamed them Puddlejumpers which was shortened to Jumpers. In this episode, Doctor McKay was able to successfully name the ship "Gateship" using the same logic that he tried in Atlantis: "It's a ship that goes through the gate."
This episode takes place in 2005 C.E. and 2995 B.C.
