James Marsters is returning for four episodes of The CW's Smallville, according to E! Online:

We last saw Marsters's character, Dr. Milton Fine (aka Brainiac), in Smallville's fifth season finale.

While it's unclear exactly how James is returning, I can tell you he's reprising the exact same character, he's returning to set very soon and his episodes begin airing in January. He also appears on CBS' Without a Trace this season.

The new season of Smallville premieres on Thursday night.
