When the various remaining members of the Avengers are reporting to Black Widow from around the world, Natasha questions Wakanda's Okoye about a series of tremors detected under the Pacific Ocean, asking, "So how are we handling it?" Okoye replies, "An earthquake under the ocean, we handle it by not handling it."
When Okoye spots Riri's amazing red car, she refers to it as a "hunk of junk" which is reminiscent of when Luke called the Millennium Falcon a piece of junk as well.
One of the FBI agents mentions Iron Man when he see Ironheart's suit in the warehouse. Riri's first flight in her Ironheart suit is reminiscent of Tony Stark's first flight in his Iron Man suit.
