Ok. Don't ask me what is exactly what (nice source EW!).
Now, we have confirmation that Michael Rosenbaum will be returning to Smallville appearing in the show's two hour season finale on May 13th:
“I’m delighted to return for the series finale,” Rosenbaum tells TVLine exclusively. “I’m simply doing it for all of the fans out there who made Smallville the great success it is. I appreciate all of their passion, their relentlessness, and even their threats. Ha ha.”
The actor continues, “I can’t wait to hug the old crew back in Vancouver one last time and see all of my old friends once again. Oh, and for Lex to become the bad-ass he’s destined to be.”
We even have confirmation from Michael Rosenbaum on twitter:
"I'm excited to come back one last time. Just promise me you'll all watch my new stuff. Then we will be even. Haha. Rock the hell on friends!"
The executive producers on Smallville, Kelly Souders and Brian Peterson, add the following:
"It feels like the stars are aligning, literally. We couldn’t be more excited. And as far as the way he returns… there’ll be no doubt about how Lex becomes the great rival in Clark Kent’s life. He is the villain of the story."
Last time we saw Lex was the season finale to season 7 - so this is a most welcome come back!
I think, this time, we can bank on the fact that Michael Rosenbaum is returning to Smallville.
