I like this idea a lot! Multi-fandom recs over a fortnight.... a very good thing :)
On the subject of recs: glammetalkitten recommended this Batman Beyond Yuletide fic to me, and now I am recommending it to you all! Blue Monday (gen). A lovely plotty story with great characterisation.
And a belated Merry Christmas, a cool Yule and Happy Holidays to my lovely flist :D
