We reported back in May that a long-running CW Network series would come to an end after this coming season and now it seems that an alum has returned. Ausiello Files is reporting that Laura Vandervoort is returning to Smallville as Supergirl.

It was said that the actress, who left the series after the seventh season, would only return for one episode in the 10th and final season of the show. The site is reporting that Vandervoort's episode is tentatively scheduled to air sometime in October. Vandervoort appeared in 21 episodes as Kara/Supergirl.

The site also directed us to an IGN article from a few weeks back which indicated that another Smallville alum, John Schneider, would return in the Season 10 premiere episode. The site wouldn't give any details of his return, since he died in Season 5, but it was also said that he was expected to appear in at least one other episode during the season as well.

We'll be sure to keep you posted on any further updates on Smallville's 10th and final season as soon as more information comes in.
