Before their conversation could continue, Lang was called to a meeting with his lawyer.

Hunting Lang

While having dinner with Maggie and Cassie Lang, Paxton received a text message from Gale which informed him that the man posing as Scott Lang's lawyer before the breakout was billionaire Hank Pym. As Paxton left to investigate the case further, he was asked by Cassie if he was going to find and arrest her father, which Paxton assured them both that he would, though he made it clear to her that all he wanted was for him to be safe. Cassie told Paxton she hoped he did not find him.

Infiltration at Pym Technologies
"All the chaos in here! Multiple shots fired... And there’s a tank."

- Jim Paxton

Paxton and his parter Gale arrived at Pym Technologies where they confronted and attempted to arrest Hank Pym, however Pym insisted that he had to get inside as he had lives to save. Although Paxton continued to insist that Pym had to come with them, they were suddenly distracted when they noticed that Dave was stealing their police car, the pair left Pym and gave chase to try and save their car. They found their car down the road having been crashed into a tree. As they made their way back to Pym Technologies they overheard a strange horn tune playing from a nearby van where Dave and Kurt were hiding, with Paxton remembered as Scott Lang's horn. Paxton and Gale walked over to the van and insisted that the pair of criminals get out, although they tried to pretend they were not there. Paxton and Gale pulled the doors open and pulled them out, but not before Kurt managed to press a button on his laptop. As Paxton and Gale handcuffed Dave and Kurt, they witnessed all the inhabitants of Pym Technologies charge out of the doors, screaming in fear. Paxton attempted to control the situation and work out what was happening, without warning a Tank, burst through the building's walls and landed by the entrance, leaving Paxton unable to explain what was happening. Paxton witnessed Hank Pym and Hope van Dyne climbing out of the tank and taking Pym for medical treatment due to a bullet wound in his shoulder. Following reports of a helicopter crash and a fight between two super-powered individuals in a family's home. When Paxton and Gale arrived, he found Scott Lang in a strange uniform, having just defeated Yellowjacket. Although Lang tried to explain what was happening and make Paxton understand, Paxton pulled out his taser and shocked Lang, knocking him out and putting him into the police car to be taken back to jail.

As they drove along, Lang woke up and insisted that Paxton needed to let him go. As they were driving a call came through the radio that a situation had occured at his home. Paxton turned the car around to drive there while Lang suddenly disappeared from the back on the car.
