Ashley rolls her eyes and then stares at him incredulously. He can't seriously be asking her why she's upset with John. Really?

"The guy tried to kill me! Granted, he was helping mom stop me and the Cabal last time I saw him - which, I know you were involved in, too, and thanks for that, by the way - but that doesn't mean I'm just going to forget what he did."

And that went for Tesla, too. She wouldn't just forget that he'd tried to kill her mother. She might be able to look past it at the moment, but she was still hesitant to just trust him.
