Ghost used to live in this mansion, where she kept the Quantum Energy Chamber Bill Foster had designed for her to help her stablilize her molecular disequilibrium. Having stolen the Mobile Laboratory from Hank Pym and Hope van Dyne, Ghost brought it back to her hideout. Exhausted by her battle against Wasp and Ant-Man, Ghost removed her suit and went into her quantum energy chamber to get some rest.
Meanwhile, Hank Pym was able to locate the hideout using a tracker reclaimed from an old Ant-Man Suit. Pym, Ant-Man and the Wasp drove to the location, which they decided to infiltrate in order to retrieve the lab. Ant-Man and the Wasp shrunk to an insect size to enter, while Pym was meant to remain outside the mansion and monitor their video feeds, although he was unable to receive a clear signal. Inside the mansion, Ant-Man and the Wasp found the Ghost Suit, as well as Ghost sleeping in her chamber, and eventually found the shruken laboratory.
However, as they reclaimed it, the Wasp realized that Ghost was no longer in her quantum energy chamber. Indeed, she had quickly left and knocked them both unconscious before capturing Pym as well. Keeping the three of them prisoners in the mansion, Ghost and Foster explained that they wanted to extract quantum energy from Janet van Dyne, still trapped in the Quantum Realm, to cure Ghost from her condition. Refusing such a plan, Ant-Man, the Wasp and Pym were able to escape from the hideout by tricking Foster into releasing giant ants, reclaiming the laboratory in the process.
