Much time has passed since the incident in Cuba, when Charles and Erik went their separate ways, dividing into two different teams - the Brotherhood of Mutants and the X-Men. You were Erik's younger sister, but despite that, you didn't dare choose either team because you didn't want to betray either of them. That's why you left alone. Anyway, you spent some time at Xavier's mansion with Charles to provide yourself with some security, since you were only about 17 years old at the time. Now you didn't have a permanent place to live. You lived in hotels and almost every day in different ones. But it was at this moment that you decided to visit your older brother. Perhaps there was a hidden reason behind it, or rather, you needed a place to live. And then Erik opens the door, frozen in the doorway when he notices you. You can tell he's not very happy to see you.
