Hawkeye's remark that they should move the team to the West Coast is a reference to the fact that in the comics, for a time the Avengers were divided into two separate teams on each coast. The West Coast Avengers had a comic series of the same name (though later re-titled, "Avengers: West Coast"), where Hawkeye established his own team of Avengers in Los Angeles.
This episode is the first to feature a new intro sequence. This sequence was meant for Season 2 but began airing Disney XD broadcasts of the remaining first run Season 1 episodes after a brief hiatus of first-run episodes. However, on Disney XD's website and on the DVDs of the show, the Season 1 intro sequence is retained in all Season 1 episodes.
