I've never really pictured Lorna as a mentor, but with it being with the O5, I could picture her having some sentimental feelings regarding them, even if they aren't the ones she knew and would lead her to wanting to watch over them. I think also because she wants to support her father right now, and with him working with them, of course she would ally herself with them as well. Outside of Jean, I'd like to see her interact with this young Bobby. I've always like the relationship between Bobby and Lorna, so I'd like to see those two form a bond.
