I don't think she'd be mad. Exasperated maybe- she wants us to know she's strong. But Aerith isn't the type to resent someone for protecting her.

[She wouldn't have indulged Daisy for four years if that wasn't the case. And Zack isn't exactly the most willing to let her fling herself into danger without some sort of guarding, either. He's still getting used to difference between Aerith of "back then" and the Aerith of today, but her kindness hasn't really budged an inch. She's never blamed someone of something they weren't responsible for. Her forgiveness of him is all the proof he needs for that.]
