WandaVision Episode 7, 'Breaking the Fourth Wall', includes the series' first mid-credits scene so make sure you hang around once the names start popping up.Unlike most Marvel Cinematic Universe fare, WandaVision's first 6 episodes haven't included extra scenes tucked in between the credit sequences (although some have guessed that the credit sequences themselves might hold clues). This week was a little different.If you want to know what was in it, scroll down.Full spoilers follow for Episode 7 of WandaVision!Breaking Through the Fourth Wall, which riffed off of mockumentary sitcoms like Modern Family and The Office, ends by confirming the long-held theory that Kathryn Hahn's Agnes is in fact Agatha Harkness, a witch originating from the Marvel comics. In a closing theme song, we're shown how Agatha has seemingly been responsible for much of the strangeness surrounding Wanda and her family, including seemingly creating or summoning Evan Peters' Pietro Maximoff.The mid-credits scene seems to confirm Pietro's connection to Agnes, as the newly powered-up Monica Rambeau explores Agnes/Agatha's house, discovers a mysterious, vine covered basement entrance and is surprised by Pietro (who's been absent for the episode) before she can enter.Exactly what all this means isn't entirely clear yet but what is clear is that we should probably be sitting through WandaVision's credit sequences every week from now on.With WandaVision fast coming to an end, you might be wondering what's to come well there's the 'good old-fashioned fun' of The Falcon and Winter Soldier beginning on March 19, and there's also a making-of documentary on WandaVision, Assembled coming on March 12.Joe Skrebels is IGN's Executive Editor of News.
