There Was a Zach Barbie Reference
In the season 4 episode “Flip Flop,” the entire family tried to help Cam and Claire sell a house. One of the interested buyers was Zach Barbie, who Haley friended on Facebook. Well, in the episode “Connection Lost,” Zach Barbie is the first friend listed on Haley’s Mutual Friends list. So clearly, she never unfriended him.
