We've all done things we regret in the name of grief. I had my sorrow cut out over continued grief after Warren was killed and reborn with no memories.
I don't think we would need to influence anyone. Technically, they're not supposed to be able to share that information without a warrant. I was doing some work with Warren before his resurrection, finding places where Archangel came into being, working to identify those memories, isolate them. That is one possibility.
My loyalty is to Rogue, and if I think she is getting worse, then I will do what I feel is right for her. If that means contacting you, then yes, of course. It also depends on what you think is "worse."
