The Casket of Ancient Winters

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.

The Avengers who appear in the screen just before the series' logo vary along with who will be in the chapter. If only Thor is going be in it, only Thor is seen.

The version that aired in Australia opened with the song "Fight as One," like the first 19 episodes, while the version aired in America included the new expository voiceover by Nick Fury.
