Hi Agatha! I know we talked briefly before and we're both somewhat canonblind to each other's games, but Emet-Selch is going to be very, very interested in her. Very. (And not in a creepy way, actually, even though Grandpa here probably seems kinda suspect...)

He's very invested in the survival/revival of the "Ancients" and even if Aerith isn't one of his world's Ancients, specifically, they've got a lot in common. He also has a connection to the lifestream and he can see souls, so I think that might be of some interest to them both.

And he just so happens to be very good with magic (he could totally help her with hers, if he wanted if he was bullied into it) and a gremlin magnet, so if nothing else I think their interactions could be hilarious!
