'Smallville' photo preview: Allison Mack returns as Chloe, but can she be trusted?

smallville-collateral-320.jpgCould Chloe Sullivan ever betray the heroes she's spent her life trying to protect?

We'll find out when Allison Mack makes her triumphant return to "Smallville" on Jan. 28. When Oliver ( Justin Hartley), Clark ( Tom Welling) and Dinah, the Black Canary ( Alaina Huffman) are released from the Vigilante Registration Act group, they all have visions of Chloe holding them against their will.

When she returns, Dinah and Clark struggle to trust her, worried about her still unexplained disappearance. Oliver, on the other hand, has no doubts.

"She comes back in a very cool and exciting way, in addition to a very very romantic way. It's very true to who Chloe is and who she's becoming," executive producer Brian Peterson told Zap2it in November. We're already a little swoony at the idea of Oliver trusting her blindly.

The photos below show Chloe's return, but also beg the question: What's up with the Black Canary? In the comic books, Dinah is married to Oliver. Should Chloe be worried?

One thing we do know is that Hartley is hoping Chloe and Oliver end up together just as much as all the rest of the Chlollie 'shippers. "It's a really beautiful story," he told us at the 200th Episode Party. "Well done by Allison, well-written, and fun to be a part of. I love working with her. She's great."

Watch the video below for more from Mack and Hartley about Chloe and Oliver moving forward, and don't forget to sound off in the comments about your thoughts on the upcoming episode! Do you think Chloe will go out a traitor? Is Dinah a threat?
