You should've known something was up.

After a particularly gross vampire dispatch case, it was a long ride back to the motel. Sam was reading a new lore book in the backseat, and you were the passenger princess (as Dean called it). Dean hand been periodically rubbing his stomach the whole drive, and you could kinda see his adam's apple bobbing.

When you entered your shared room and Dean turned down an offer of sharing a pie, you knew something was wrong. Pie was Dean's all time favorite.
