Yeah, Sam's story is one of my absolute favorites; I've read another John/David Tennant series that I don't absolutely hate (but it's by an author who I can't stand so I feel weird about fanning their work; it troubles me when I dislike published authors, and yet appreciate their work; somehow it's worse when they're fan-authors, and you know, in the same community.) I've yet to read a John/Gareth one worthy of a second read, but I keep hoping. Oh, and I think I read a fairly decent John/Naoko one (sorta, it didn't really go anywhere) taking place at a Torchwood wrap party. That's pretty much the sum total of memorable stuff, as far as I can remember.
