"I don't know," Peter admits. "I'm not sure if it's possible for her to freak out more than she has already."

It's true. It was even worse than the time with the ferry. If he hadn't been so upset then, she probably would have been more upset than she wound up being.

May really cared about him. And that's why she was freaking out. Even though he didn't realize it at the time, he was pretty sure Mr. Stark felt the same way, even though Peter was sure he wouldn't ever admit it.
