I highly recommend foxypadawan's Halloween, a story that can be read as slash, pre-slash or strong friendship. It's set post-TDK and features Jim and Bruce. She had asked for prompts and of course I had to ask for something Halloween-related! ;)
The personalities of Jim and Bruce are perfectly done, as are their views of Halloween in Gotham. The story has drama and touches of humor. Her writing is poetic in flow and craft.
There's an excellent final scene between the two of them, too.
