After a four year-absence from the MCU, Gwyneth Paltrow reprised Pepper Potts later year for a cameo towards the end of Spider-Man: Homecoming, and she also briefly returned earlier this year in Avengers: Infinity War.
That being said, it appears that Pepper may have survived, as back in May, Paltrow stated that when we see Tony and Pepper in Avengers 4, they’re now married and have a child.
We all know how that turned out, but the movie didn’t reveal if Pepper was one of the people who faded away after the Thanos snap.
With Tony and Pepper finally having patched things up, the two are now engaged, but while the couple were chatting in Central Park at the beginning of Infinity War, Tony was pulled away by Doctor Strange to join the coming battle against Thanos and his forces.
