Hey, I was recently re-watching the first season of Veronica Mars, and I recalled a really great VM/SPN crossover where Sam was Logan's roommate at college, and therefore friends by proxy with the whole group. I think he got involved in the detective business at some point in the story.

If anyone could provide the link, I'd really appreciate it! I've looked all over sn_crossovers and supernaturalfic and I can't find it. :(

ETA: Found! by seedyapartment: Normal Is The Watchword. Thanks! :D
