Diversionary Tactics by Shrift [Dan/Casey]
Uhm, wow, okay, awesome. Let me say straight off that I hate phone conversations, but that the show's dialogue seems to lend itself to it, and the author here has really picked up on it. I mean, the back-and-forth just works awesomely, and considering Dan and Casey aren't even in the same room for 90% of the story, I was head over heels for it. Really, really excellent.

This really could be an episode if it had the chance. It's got great use of all the characters, an actual problem, awesome interaction and dialogue... I don't know what to say other than that it is pure sports night as it should be.
