History
Henry Pym shared personal history with Henry Pym of Earth-616 up until the point of temporal divergence caused by the arrival of Gwen Stacy of Earth-65 into his universe.[1]
Gwen-65 along with the native Gwen Stacy of Earth-617 visited the Avengers Mansion to ask Tony Stark for help. They revealed the existence of alternate realities and the Multiverse, asking to verify the calculations Gwen-617 made on the Empire State University computer. Dr. Pym and Stark got busy looking into the details of the data brought to them, and Stark provided the girls with a device that could possibly help Gwen-65 return to her home.[1]
