Hi! I'm searching for a completed Sam/Dean fic where the boys pretend to be a couple to investigate some mysterious happenings on a bus trip through Nova Scotia? And Sam kept being hit on by one of the passengers, and Dean got pretty jealous. It was an awesome, slow build-up -- I could've sworn the author's username was flawedamethyst but perhaps it's something very similar to that.

Thanks in advance!

Found in comments! (Almost immediately too, wow!)
