"Really?" Dean's eyebrows jumped.

"Yeah. Sunk in a storm in 1723. Headed to the New World…?" Sam took Dean's cues to keep going. "Weighed anchor in Leith, Scotland."

"Leith!" The older brother snapped his fingers. "Gavin MacLeod. This- this was his ship."

"Crowley's kid?"

"Yeeep," Dean nodded, looking proud of himself.

"... How do you know that?"

The smirk faded. "Well, uh… I dunno."

Sam couldn't help himself. "Does this have to do with that 'summer of love' thing from a couple years ago?"

Dean looked taken aback, horrified, and disgusted all in one. "No."
