Five years later, Scott Lang escapes from the quantum realm. [N 2] At the Avengers compound, he explains to Romanoff and Rogers that he experienced only five hours while trapped, instead of years. Theorizing the quantum realm could allow time travel, the three ask Stark to help them retrieve the Stones from the past to reverse Thanos's actions in the present. Stark refuses, thinking of his wife, Pepper Potts, and daughter, Morgan, but relents after thinking back to the death of Peter Parker. Stark and Banner, who has since merged his intelligence with the Hulk's strength, build a time machine. Banner notes changing the past does not affect their present; any changes instead create branched alternate realities. He and Rocket visit the Asgardian refugees' new home in Norway—New Asgard—to recruit Thor, now overweight and drinking heavily, despondent over his failure to stop Thanos. In Tokyo, Romanoff recruits Clint Barton, now a violent vigilante following Thanos's disintegration of his family.
