While fans wait with bated breath for news that Michale Rosenbaum will reprise his role as Lex Luthor, original Smallville cast member Allison Mack will return as Chloe on the January 28th episode, entitled "Collateral". Alaina Huffman, who plays the Smallville version of Black Canary, will also make an appearance. The two come into conflict with Oliver Queen/Green Arrow over Chloe's intentions.
Chloe Sullivan's last appearance on Smallville was the season 10 premiere, where she and long-time love interest Oliver Queen (played by Justin Hartley) were dramatically ripped apart. Chloe left with the knowledge of Doctor Fate after faking her own death and hasn't been seen since.
"Collateral", will see them reunited - though with only a handful of episodes left, they'll have to talk fast if fans are to see a happy ending for Smalliville's original girl reporter. Dinah, AKA Black Canary, has made fleeting appearances this season, but will return in earnest as the series ramps up to the finale.
Chloe's return won't come without it's own complications. Her intentions are far from clear, and Black Canary fears that Chloe may have turned traitor since the events in the premiere. The central conflict will revolve around Chloe's mysterious disappearance, and whether or not Clark and the others can trust her. It's not clear if Chloe will resume her duties at the Watchtower (or as Watchtower, for that matter) but given the character's on-again, off-again powers, various interests and her recent disappearance, it would seem that anything is possible. The Suicide Squad will also make an appearance.
TV Line speculates that Black Canary and Green Arrow may be headed for a more serious relationship in the last few episodes. They offer the recent marriage of Black Canary and Green Arrow in the DC comic continuity as evidence. This seems unlikely, however, given Chloe's more established role in Smallville's continuity and the fact that the show's writers never feel compelled to use the comics as anything more than a guideline. We've seen over 200 episodes without Clark donning the blue tights, so why start walking the continuity tightrope now?
One thing's for sure: those waiting to see Clark finally seize his destiny are in for a treat very soon. Comes the hour, comes the man - and there aren't that many hours left. The recent promotional art for the last half of season 10 doesn't leave much room for interpretation.
Smallville returns to the CW on Friday, January 28th.
