The Stein Mansion was the place of living of Victor, Janet and Chase Stein in Los Angeles.


Tense Family Life

While he was training in his room, Chase Stein was asked by his mother Janet Stein to come for breakfast. Chase joined his father Victor Stein at the table, who blamed his son for his mediocre grade in a Spanish exam. Victor claimed that Chase should fear him more so he would have better school results.[1] Later, Chase and Janet talked about Victor in the former's bedroom, and Chase fully expressed how much he disliked his own father.

Janet went down to find Victor in his lab, where he worked on the Dematerialization Box, attempting to fix it for the upcoming Rite of Blood despite his violent headaches. When Janet suggested that Victor could ask for help, he abruptly rejected such an idea before apologizing to his wife.[2]

Following the failed sacrifice of Destiny Gonzalez, Victor spent a whole night in his lab, occasionally hallucinating on Gonzalez who he had murdered. Janet then came to tell him that they were late for a dinner and suggested that Victor had more problems that he disclosed, but Victor once again rebuked his wife, claming that she had to fully support him.[3]

Having witnessed the Rite of Blood, Chase Stein and Gert Yorkes went to the Stein Mansion in order to find clues explaining what they had seen. They searched through Victor Stein's lab and found the hidden Dematerialization Box. As it was empty, Chase and Yorkes decided to leave the mansion and to carry on their investigation in the Yorkes Residence.[3]

Later, Chase returned to his bedroom and had a video call with the rest of the Runaways where they shared the tiny results of their investigation and the recent discovery of Destiny Gonzalez's corpse. Chase then ended the call and kept working on his Fistigons, as he wanted to use them to prevent their parents from harming anyone else.[4]

Paternal Bonding

In order to further develop the Fistigons, Chase Stein decided to use his father Victor Stein's lab. Victor got back home and found his son working in his lab. Victor took the still not functional Fistigons and briefly inspected them before dropping them. Chase expected his father to blame him, but much to his surprise, Victor asked his son to explain his idea and began giving him advice to achieve his project.[4]

While they worked together on the Fistigons, Victor admitted that he had been tough to Chase but that he was convinced that his son could become someone truly important. Although surprised, Chase was glad to be able to bond with his father by working with him in the mansion's garage. However, Chase left the mansion with the Fistigons when he was informed of the Kidnapping of Alex Wilder.


Chase and Victor Stein work on Victor Stein's Time Machine

Victor and Janet Stein also left the mansion to perform a final Rite of Blood. Victor then returned to the garage, soon followed by Chase. Deciding to further work with his son, Victor told him about an invention he had been developing for years: a time machine able to show images of the future or the past.

However, their first trial with the machine failed, triggering another anger spike associated with a headache for Victor. Deciding that he could no longer keep the truth for himself, Victor revealed to his son that he suffered from a brain cancer. After they shared a hug, both Victor and Chase left the garage, unaware that the machine dropped on the ground displayed images of a future destruction of Los Angeles.[5]

Despite Victor's reveal, he and Chase kept working on the Fistigons in the mansion' garage. Once his son left to prepare for the upcoming PRIDE gala, Victor remained alone in the lab and listened to a conversation between Janet and her lover Robert Minoru, as he had begun to spy on his wife's phone.[6]

As Victor had once again fallen asleep in the mansion's lab, he was awakened by his time machine, which displayed a picture of an adult Chase begging his father not to pick up the Fistigons and apologizing to Victor. Later, Chase joined his father as he successfully did some calculations to improve a battery manufactured by Nemo. Chase noticed that his relationship with his father had improved even more after Jonah gave Victor a mysterious treatment, which seemed to completely change Victor's personality.

Victor then left the garage, leaving Chase and Janet in the garage to talk about Janet's affair with Minoru, although Janet promised that she would do anything to keep her family unharmed.[7]

Attack on Victor Stein

However, Victor Stein eventually returned to his harsh and unforgiving personality. Once he got back from the Atlas Academy's open house, he confronted his son Chase Stein about his presence in the lab, something Chase did not understand as they had spent hours together working on the Fistigons. Father and son began to argue, which escalated to a fight as Victor attempted to hit his son, who punched him back. Victor then took the Fistigons and fired at Chase, throwing him through a window. As Victor prepared to hit his son again, he was shot by Janet Stein with the gun Robert Minoru had given her.[7]

As she could not call the police, Janet instead informed the other members of PRIDE. Robert and Tina Minoru were the first to arrive in the mansion, followed by Geoffrey and Catherine Wilder. While Janet and Chase talked about Victor's anger in the kitchen, Dale and Stacey Yorkes also arrived in the mansion. Meanwhile, Chase went to his bedroom and sought some emotional support. He called Gert Yorkes, who did not answer, and Karolina Dean, telling her that something had happened and asking her to come to the mansion before changing his mind and hanging up.

PRIDE attempts to save Victor Stein

Having learned about Victor, Leslie Dean also arrived into the mansion as Dale announced that Victor had fallen into a coma. Leslie asked her husband Frank to come to the mansion as well to save Victor with his Healing Gloves. Frank arrived and used his gloves, but the operation failed and Victor died.

Minutes later, Gert and Karolina also arrived to the mansion to support Chase. As they parked their car, they noticed the arrival of Jonah who had been informed by Tina. Jonah joined the other members of PRIDE in the garage and explained that he would resurrect Victor by using the Dematerialization Boxes. However, he needed a sacrifice for that and suggested Janet to give his life for Victor. An argument erupted between the members of PRIDE. In the end, Robert was willing to sacrifice, but Tina refused to lose her husband and destroyed one of the Dematerialization Boxes, thus rendering the sacrifice impossible. Victor's body was then taken out in the remaining Box.[8]

Like the residences of the other members of PRIDE, the Stein Mansion was a large and wealthy home with two floors.

The lab was located next to the mansion's garage, which hosted several expensive cars.
