The sands keep shifting underneath the couples on this show. Just when it looked as though Sarah (Lauren Graham) might get back together with resurfaced ex-boyfriend Mark (Jason Ritter), he announced his engagement… to someone else. Just when it appeared Zeek (Craig T. Nelson) might sell the house, maybe he won’t. And just when it seemed Julia (Erika Christensen) and Joel (Sam Jaeger) might gravitate back together, she pursues her interest with another man. Things change week to week on this show, just as in life.
