After witnessing Oliver's abduction through a video feed, Chloe exhausted her resources to try to find him, eventually resorting to using the Helmet of Nabu, which rendered her unconscious. Once she recovered, she relayed part of what she had seen to Clark and sent him to Cadmus Labs to extinguish a fire and stop Lex's clone. Chloe said goodbye to Clark and later traded herself for Oliver in order to save him. Although Chloe was lost, Oliver continued to remind her and revealed that they shared their first kiss on the Watchtower after her first lesson in archery.
