Annie and Eric decide to renew their wedding vows on their upcoming nineteenth anniversary, but the kids don't share their enthusiasm. Lucy broods over the fact that Jimmy Moon is now dating her rival Ashleigh, while Mary is sour about knee rehab and is becoming distant with her boyfriend. Simon expresses a desire to move out of the room he shared with Ruthie. Eric does his best to offer closure to the widow of a murder victim.

Simon can't resists reading Matt's letters and thus discovers big brother is secretly married to Heather. Eric can't resist spying on both, and thus falls into a trap. Wilson won't say 'I love you' back to Mary, who refuses to understand he'll only say that again when even more serious then with Billie's late ma. Lucy's friend, new girl at school Laurie, is extremely timid due to her verbally brutal ma, but the scolding root sits deeper.
