Kitty/Illyana
She did get another chance, but our world isn't very fair. She died of the Legacy Virus. That's why I was so surprised and emotional to see you. I'm sorry. Piotr died too, or so I thought, he died curing the Legacy Virus in your name. But he came back and I guess you came back with Darkchilde in control and looking for the Soulsword. Plus there was a disaster involving the Phoenix Force taking over you and Piotr for awhile. This all happened past my memory, I don't know the details.
