Cathy still isn't feeling like she can let Paul back in the house or in her life. Adam is still angry with her and avoids her at all cost. And Sean still believes that Cathy is too uptight with who to hang out. So at this crucial time in her life, Cathy is feeling all alone, that is except for Thomas, Marlene's beagle, who always seems to be following her around. Her attempts at bringing Sean - and his girlfriend Daphne - and Adam and Andrea as meaningful parts of her life don't end up quite the way she envisions. As such, Cathy decides to attend a cancer support group. But those in the group end up being way too happy and upbeat for her liking, they seeing their cancer as it is a gift. Regardless, the support group appoints itself as her "Team Cathy" whether she likes it or not, as they believe that she really does need someone in her life for support. She has to decide if Paul is a better option, he who really does want to move back in. Thomas may find Cathy an unexpected substitute.
