Zach and Kendall's romance is shot to crumbs when Kendall learns that Zach caused the blackout which spun her in the position of having to carry her own child with Ryan instead of Greenlee's. Zach voices to Kendall that he arranged the blackout to sabotage her chances of surrogacy because he wanted to protect her from a dangerous Ryan. Kendall does not care for Zach's reasons and breaks off her romantic ties to him, just as she is not feeling the maternal instinct. Zach also loses his son, Ethan, to death around this same time, and loses Kendall as well.
