Zach comes into the knowledge that Kendall agreed to act as the surrogate for Ryan and Greenlee's baby when Greenlee's chances of giving birth became non-existent. He utterly hates the idea, and is determined to ensure Kendall will not go through with it. Once Ryan reveals himself to be alive a little after this, Kendall comes to the shocking realization that her husband helped Ryan fake his death. She is enraged at Zach, and states that she never would have taken on the task of being Greenlee's surrogate if she had known that Ryan is alive. Zach and Kendall fight on and off, but no matter their argumentative nature, Zach has developed true romantic feelings for Kendall. At this point, Greenlee has discovered that Kendall is pregnant not with Greenlee and Ryan's baby, but rather with Kendall and Ryan's baby. She spills this knowledge to the whole town, stating that Kendall has betrayed her in order to produce a child between Ryan and herself. Kendall is embarrassed and heartbroken at Greenlee's accusation, and tries to explain that Greenlee's eggs had been destroyed at implantation time, and if she had not used her own eggs, Greenlee would have been without Ryan's child for certain. Greenlee does not care to listen and soon leaves town. Zach sticks by Kendall's side and tells her of his love for her. Kendall is afraid of his declaration, and starts to distance herself from him. She asks for a divorce, not admitting that she feels the same way. Zach agrees to grant her a divorce, but Bianca Montgomery, Kendall's sister, counsels Zach to not give up on Kendall. Zach does as suggested, and informs Kendall of his love for her again. This time Kendall does not hold back and the two share a passionate kiss.
