Lorna coming in an update with Havok makes sense bc they tend to introduce characters in a theme and she is very linked to him. If not Alex, I would have expected a Magnus family theme update with her but considering Pietro and Wanda just got an update and technically still arent officially a part of the family, then thats not likely to happen in the near future. I could see a Women of X-men themed update with her

The whole clone issue being why she wasnt added in the past is BS now considering the roster is close to or over 200 characters, many of whom are very similar to another. Plus costumes changes movesets making some play likely completely different characters
