- The episode's cold open, set during Avengers: Endgame, has voice-over from dialogue in the film Captain Marvel.
- The episode confirms the events of the series take place three weeks after people returning from the Blip in Avengers: Endgame.
- Jimmy Woo uses a card trick to bring out his calling card when meeting Monica Rambeau. He picked up this trick from Scott Lang in the film Ant-Man and the Wasp.
- The S.W.O.R.D. jeep Monica drives is marked S-8512 on the side, which could be a reference to the the 1985 12-issue limited run of Vision and the Scarlet Witch (Vol. 2), which this streaming series heavily draws inspiration from.
- The colors of the drone Monica flies into Westview are the same colors of Captain Marvel's suit, which Monica helped choose in the 1990s.
- The Vision's deceased form that briefly appears at the end of the episode is reminiscent of the "colorless" version of Vision from when his matrix of emotions was removed in the comics.
