The "Ask Ausiello" feature at TVline.com has a couple of entries relating to "Smallville".
Question: I know he's technically dead, but any chance Davis Bloome will return to Smallville before the final episode?
Ausiello: There was talk of bringing back Doomsday's alter ego, according to portrayer Sam Witwer. "At one point, they were thinking maybe [Davis] could come back and do something, but I don't think they cracked how," he reveals. "The way that they left it, it would take a bit of work to get him back into the fold. So no, I don't think we're going to see Davis Bloome again." Although he hasn't kept up with Smallville since he left, Witwer plans to catch the May 13 series finale. "I'll tune in to see him put on the cape," he says, "if ever he chooses to do so."
Question: With the news that Lex and Kara will be returning to Smallville, what are the odds that Terrence Stamp will appear as Jor-El?
Ausiello: Vegas oddsmakers put his chances of him returning in the flesh at 90-1. But here's where things get interesting: The odds of him coming back in a strictly voiceover capacity are 2-1.
