The barely intelligible words at the beginning of the episode while Monica is coming back from the blip are pieces of dialogue from Captain Marvel (2019), where Monica was just a child. It's like her mind is recomposing itself by experiencing again every memory in Monica's life.
The pre-credits sequence takes place in the middle of Avengers: Endgame (2019). When Hulk snaps his fingers in that movie, restoring half the world's population, Monica Rambeau materializes in the hospital in the opening scene. After the Marvel Studios logo, the rest of story takes place three weeks later, in the year 2023.
One of the local cops calls Agent Woo a "G-Man," slang for FBI Agent. In the Marvel comic books, Jimmy Woo was a member of the superhero team "G-Men," also known as "Department Zero," later renamed "Agents of Atlas."
The drone helicopter that Monica deploys just outside Westview is painted in Captain Marvel's signature blue, red, and yellow color scheme.
