I don't imagine Lorna to be too personally aggressive towards Wanda over the numerous debacles she's been involved in.
It is a shame that sense of family unity from Children's Crusade has disappeared with AvX, though, saying that- I feel that familial touch may still be there... the tensions between Wanda and Magneto in AvX seemed more political than personal as they had that moment during the final battle... Pietro probably still holds some personal animosity towards his father due to AvX.
I think Lorna's impersonal attitude towards Wanda probably signifies a lot of how she views her... she doesn't think much of her. Wanda, however, I can see being resentful towards Lorna for having been allied to Magneto too much and being so willing to fight her during AvX. Lorna would probably have a one line put down if Wanda ever gets iffy with her.
It's Lorna's attitude towards Magneto which should be most interesting. It could go a number of ways... I think she's most probably still not willing, or ready, to approach him after the revelation about the plane crash. If she stays in character I don't see her holding a grudge regarding not telling her directly- she's never been the type- but obviously I do think she would've preferred he told her rather than assuming he knew best, deciding to avoid her for most of her life and go on with his way instead. I think she could also give him the benefit of the doubt regarding his current circumstances- not his fault he's on the run, obviously its not like she would expect him to hand himself in (Magneto's line to Storm in Consequences #4 rings rue here).
BTW those cosplay outfits are amazing :D
