In 2008, when Kendall discovers that Greenlee is not responsible for Spike being deaf after all, she feels great remorse for having exacted revenge against her. Soon, Greenlee and Zach go missing. After searching for the pair for weeks, Kendall and Aidan Devane (Greenlee's boyfriend) believe them to be dead. The two have sex during their grief. Afterwards, however, they discover their lovers alive. Overjoyed by this turn of events but also full of dread due to fear of their night together being revealed, Kendall and Aidan try to get back the sense of normalcy they had before. But matters become more complicated when Kendall finds out that she may be pregnant, and unsure of who the father is — Zach or Aidan. She takes a pregnancy test and is relieved when the test result is negative. She struggles to keep her conscience clear regarding her night with Aidan, however. Eventually, she reveals to Zach that she and Aidan had sex. Zach, who had already suspected (and knew) after putting "clues" together, has a difficult time accepting it at first, but soon forgives her. Zach and Kendall try to move on with their lives, all the while keeping Kendall and Aidan's tryst a secret from Greenlee.
