Sue Storm & Leia Organa
Sue felt badly for Leia to have only just found out that she had a brother at all. That must have been very confusing all around, but at least in Madison, they would have all the time they could get to come to terms with everything. It wasn't an easy thing, obviously, but hopefully they'd have time enough.
"I wish you all the best," Sue replied honestly. "And if you've ever a need to complain about annoying brothers, I'm more than happy to lend an ear." She doubted anyone could be as annoying as Johnny but it could certainly get to a point where she'd need to vent. Sue understood it better than most.
