I think she couldn't, she couldn't give too much away! Even about Rachel it was more about how Rachel, Lorna, and Northstar are both going through things that draw them close together as friends in the book! It sounds like the three of them are the tightest part of the team!
You know what I want to see, is Lorna have occasional meals with her father! Just simple family stuff, I would love that if the rare times that Magneto just acts normal is when he is with Lorna! He already appears to be a more open and honest with Lorna then he is with everyone else, so I think he is trying really hard to have a good relationship with his daughter and make up for past mistakes! Probably a bit haunted by what happened with Wanda and Pietro and realizing he needs to work hard to make sure he can have a good relationship with the only family he has left!
