Just when it seemed like their caper was going smoothly, Pym got an unexpected visit from Cross. Lang and van Dyne concealed themselves, as the former commanded his ants to conceal evidence of their caper. After Cross left Pym's house, he called van Dyne, announcing his intention to increase security at Pym Tech. Realizing their plan had hit a snag, Lang brought in his associates, Luis, Dave and Kurt in on the caper.
"Did you think you could stop the future with a heist?!" "It was never just a heist!"
The moment Lang landed in the container that was holding the Yellowjacket suit, Cross took the suit out. Lang was stuck until he used one of his Pym Particles Disks and broke out. During the confusion of Lang's escape, Mitchell Carson escaped with the imitation Pym Particles, while being attacked by ants. Cross shot Pym before escaping with the Yellowjacket suit. van Dyne told Lang to get Cross while she took care of Pym. During Lang's escape, he was attacked by security. He was almost dead until Luis saved him. Pym and van Dyne escaped using a Shrunken Tank that Pym used as a key chain, and Pym Technologies was imploded, using the charges set by Lang.
Cross escaped to his helicopter with Lang and the ants in hot pursuit. Cross defended himself with a pistol and started shooting, one bullet hitting Ant-thony head-on, forcing Lang to ride another carpenter ant, vowing revenge. Lang clung onto the helicopter and fought Cross and his two guards. With his guards disabled, Cross donned the Yellowjacket Suit and fought against Lang. The two fought inside Cross' briefcase before the aircraft crashed into a household backyard.
Landing in the backyard, Darren Cross threatened the resident family until Scott Lang stopped Cross, and they continued their fight. Lang managed to swat Cross into a bug zapper; however, Jim Paxton appeared and electrocuted Lang, proceeding to arrest him. Cross then got zapped by the bug zapper, acting like a defibrillator, coming back to life but proceeded to Maggie Lang's House.
The whole incident gave Leo Fitz the idea that Jemma Simmons might be missing because she was shrunken to a microscopic level, which turned out to be false.
