I remember trawling the intarwebs for Chuck/Casey fic a while back! I found some! And then promptly lost them after I finished reading! D: I should hunt them down again and bombard you with links.

Bryce got amnesia after being shot so many times. And then the CIA downloaded a new set of memories into his brain, so now he thinks he's an art thief named Neal. One day, the FBI and the CIA are going to overlap on a case and Neal will meet Chuck and then ~*things*~ will happen. :D (you do watch White Collar, right? :D;;)

I adore buddyships (e.g. my epic love for J2 and Bruno/Boots-of-the-teeny-fandom-that-no-one-knows-about), but I think I have a tendency to gravitate towards antagonistic ships (not necessarily full-on rivals, just a bit of hate + love + grudging respect -- but I do like me some full-on rivalry when available ;)).

Hee, the great thing about AS/S is that it could be written as a rival ship or a buddyship or the catalyst for bringing together Harry and Draco. I totally thought Luna/Ron was a viable ship for a while! And then HBP came out and my shippy heart was broken into a million pieces. Also, Luna is awesome -- especially movie!Luna. :D
