"You can stop thanking me and stuff now," said Raph, vaguely discomfited by it.

Mostly because he wasn't used to it. No one even knew they did nice stuff or helped people, let alone thanked them for it. It felt...weird.

"It's weird," he blurted out before realizing that might come off like he was saying that it was weird Dean was thanking him and not that it was just weird to hear it. "I mean, I get you're trying to be appreciative. I'm just not used to it. No one thanks us back home."

Even hunters got the occasional 'thank you for saving my life.'

"Anyway, the myths that attacked us were some weird British action movie villain type guy named Benedict, Bloody Mary - as in the Bloody Mary - and The Trunchbull from that movie with the girl who can move stuff with her brain. They beat us senseless and dumped us in Times Square with these collars that suppressed our myth powers and tipped off these government agents that we were there. Then they took us to this creepy government lab and - and Nico and the twins got us out."

He didn't go into what had happened in said lab because he really didn't want to.
