アベンジャーズ/エイジ・オブ・ウルトロン
Executive producer Maurissa Tancharoen stated the production team was not ruling out creating crossover episodes with "Agent Carter" or "Guardians of the Galaxy" during the season, with executive producer Jed Whedon adding that any such episodes would not equal the scale seen in the ' crossover from the first season, saying, "In terms of game-changers, [those episodes are] hard to beat." Bell later said ' "is coming up and we know what's going on with that and look forward to seeing it, but it's pretty cool to find ways to tie-in stuff and connect things." In December 2014, ABC confirmed the series would tie-in with "Avengers: Age of Ultron", with Whedon saying, "You should expect something. "The Avengers" is the big tent that all the franchises play under. Obviously, we're included in that." The episodes "The Frenemy of My Enemy" and "The Dirty Half Dozen" feature "Easter eggs, plot threads and other connective tissue leading into the opening scene of "Avengers: Age of Ultron"" while "Scars" explores the aftermath of the film.
