An extended scene of the opening flashback, showing a younger Hank Pym and Janet van Dyne in the 1980s.
Pym wears the Ant-Man Suit punching a soldier, then Van Dyne in her Wasp Suit regrowing mid-flight and knocking the soldier down to the ground. Hank Pym and Janet van Dyne go on a mission in Buenos Aires to capture Elihas Starr. During the mission, some of Starr's own soldiers accidentally shoot at the Quantum Tunnel, causing it to go into overload, killing Starr while Pym and van Dyne are able to escape.
Then ava's parents were killed after janet and hank succeeded the mission. Then what was ava's & bill's actual birth of date? it was miscalculated for them young in 1995.
