On January 28, Smallville won't just return with a new episode titled "Collateral."
It will also reunite Chloe with Oliver.
Allison Mack will make her first appearance on the show since the season premiere. As seen here, Chloe will be anxious to meet up with the man for whom she gave up her freedom in September, handing herself over to the Suicide Squad:
“They’re going to get together and talk about what happened, why she left,” Justin Hartley told TV Line. “They’ll try to patch things up."Oliver and Chloe will also spend time with Alaina Huffman's Black Canary, the character the former actually marries in DC Comics lore. It's unknown in what relationship direction the series will go.
But we do know that Mack will stick around for five of the final Smallville episodes.
