I didnt, until you mentioned it and I went back to see. LOL! Im sure it was intentional. Just like the episode recently which had "Joe M" on the door of the asylum where the Lycans were, and he got eaten by another werewolf. ONLY him.
Actors and writers who have had the unfortunate pleasure of working with Joe M on Stargate could leave plenty of "easter eggs" like that for months to come.
If I was treated like shit by Mozz, I would have a bone to pick with him too. I wonder if stuff will come out after the SGU actors are no longer on the contract?
Thing is, I dont necessarily think its Amanda Tapping dropping these easter eggs. I think its Damian Kindler, who previously wrote for Stargate SG-1 and Stargate Atlantis. I imagine his experience with Mallozzi was unpleasant. Look him up!
