Tom Welling

Smallville  opened the final day of Comic-Con with a super-sized bang. The cast and producers of the CW series dished out more spoilers than we can wrap our heads around. From Allison Mack's exit and the introduction of the super-suit (which is actually the very suit from Superman Returns), to new villains and resurrections, TVGuide.com has all the scoop below:  

Super Season 10 Scene-Stealers: New footage from the final season kicked off the panel. Spoilers of note: Lois (Erica Durance) finds the infamous blue and red super-suit in the Kent farmhouse; Chloe and Oliver (Justin Hartley) kiss; Tess Mercer (Cassidy Freeman) is still alive, but being held captive; Cat Grant joins Clark (Tom Welling) at the Daily Planet while Lois is off in Africa as a field correspondent; we hear the word "Superman"; and Chloe says "Goodbye Clark," as she picks up Dr. Fate's gold helmet. Is your head spinning?

Super Villain: "This year we have a little different twist on the villain," executive producer Brian Peterson  said. "We're bringing in Darkseid, but he's going to come in a little different form than you're used to seeing, so we're going to switch it up a little."

Super Secrets: Lois found out Clark's little secret in the season finale, but won't be sharing the news, even with him. "She decides not to tell him that she knows for a while," Durance told TVGuide.com after the panel."She finds all these ways to hide it and make it easy for him to do what he's got to do to get away from her, so he can be that superhero and fulfill that destiny. But, in true Lois fashion, I'm sure she'll get tired of keeping secrets."

Super Surprise: As mentioned above, Tess Mercer is alive. Rejoice! She will even be helping Clark and Oliver at Watchtower, Freeman told TVGuide.com. However, "There's a huge secret from her past discovered in mid-season that is going to come back, that she tries to keep from people, but it's really going to change things around for her. This twist is going to define whether or not she's destined for goodness or badness."

Super Endings: Mack will be leaving the show this season, and Peterson said they will wrap the storyline "in a way that's fitting for Chloe." Her romance with Oliver will play a key role in that. "She gives herself up for him, like a trade almost," Hartley told TVGuide.com. "He is trying to figure out who's behind it, and he's been told that they killed her, so he's kind of tormented. His whole quest is to try to figure out where she is."

Super Behind-the-Scenes: Welling will be directing two episodes in the new season, and Hartley will take his first spin in the director's chair. There's also good news for Durance fans that campaigned for her to be in 22 episodes: Mission accomplished.

Super Returning Characters: Jonathan Kent (played by John Schneider, who surprised fans by showing up to the panel) will return, along with Brainiac (James Marsters), Kara (Laura Vandervoort) Carter Hall (Michael Shanks) and Plastique (Jessica Parker Kennedy), who has become a member of the Suicide Squad. Peterson also said they're in discussions to get Lionel Luther (John Glover) back on the series. And as for his progeny, Lex (Michael Rosenbaum), the producers said the door was always open.

Super New Characters: Besides Granny Goodness, who appeared in the finale, and Darkseid, along with his harbingers, viewers will meet Rick Flag, a member of the Suicide Squad. Also, Geoff Johns, who wrote "Absolute Justice" last season, will be doing a Booster Gold and Blue Beetle episode that will feature Jaime Reyes' Blue Beetle, Skeets, and possibly Ted Kord.

Super Wait: Clark Kent will become Superman by the end of the year. "There are some people who don't like the fact that we've waited this long to do the suit or become Superman," Welling told TVGuide.com. "You also have to understand that if we had done that in Season 1, we would've been done. The fact that we've lasted this long is because we've struggled and tried to put off the inevitable this long."

Smallville premieres Friday, Sept. 24 at 8/7c on the CW.
