Why This Must Be Read: Summary: Mary and Marshall take the show on the road in an assignment that turns hazardous and forces them into exploring the dynamics that shape their relationship. A great look at their dynamic, and the characterization and voices are spot-on. I wasn't even looking for M/M fics, but I stumbled onto this gem, and yes. This is them. This is them as I couldn't have even imagined, but it works because the foundation is all there in the show.
