1 mistake in Quarantine
Starring: Jason Momoa, David Hewlett, Joe Flanigan, Rachel Luttrell
Dr. Rodney McKay: Did I mention that I know almost everything about almost everything?
Trivia: In the final episode, 'Enemy at the gates' Sam Carter says that the new ship is to be named the General George Hammond in memory of the character Hammond who had died of a heart attack. This is a tribute to Don S. Davies, who played Hammond, who sadly died of a heart attack in June 2008, shortly after filming Stargate Continium.
Question: When the ancients return to Atlantis they are greeted by 2 star general O'Neill but later in that episode and the part 2 episode he only had one star on his uniform. This same thing happened in a SG-1 episode when Dr. Jackson became a prior for the Ori.
