Sam doesn't jump but tilts his head in confusion as the shake appears. "Huh..." he looks over to Dean and raised his eyebrows at him in a "the fuck?" kind of look. He pauses in thought and looks back to Jake. "Wait... you're only 16? Seriously?" He could have sworn the 'kid' was at least 20 if not older with how he acts. I mean, 16? Jesus... He was barely even old enough to drive in their world. Wait... didn't he have a boyfriend that was like 2 years younger than him?
Sam tilts his head, staring at the bar, thinking to himself. Does that mean he's screwing a 14 year old? Sam's eyes went wide at his realization. Not only was the kid underage, he was having sex with another underage kid! Younger than him no less! The fuck?! Sam shook his head and cleared his throat, waiting for Jake's response. Oh this better be good.
