St John was decidedly 'why the fuck not' about a lot of things; Raven was one of them. She was as crazy as they came, sure, but sometimes it was narrowly focused on some very specific things that John could get behind. And if she wanted to blow off some steam, then blow some stuff up, John was game -Raven was in no way the type to get attached to anyone, which John appreciated. It was just sex. With a completely new person every time.
But then there was the psycho crazy in her that really just frustrated Pyro with her serious control issues. "You know what would be easier?" John had to make two turns to find the other turn she'd wanted, "Giving me a fucking destination to go to rather than 'turn left, turn right', especially when you're telling me when I reach the fucking turn." Seriously, could no one just tell him where to go rather than being so fucking awkward about shit?
