By the end of the season, Jen Harding turns herself in for murder but is given a break.
After ending season one by killing Steve Wood (James Marsden) in a blind rage, Jen (Christina Applegate) spends the majority of the second season dealing with her fear of getting caught.
Viewers learn that Jen called Judy (Linda Cardellini) right after she killed Steve, and the two become accomplices even though they were still at odds.
Throughout season two, Jen and Judy hide their secret from Jen’s two sons, Charlie (Sam McCarthy) and Henry (Luke Roessler). Eventually, Jen lets Judy move back in.
Jen also learns that Steve has an identical twin — Ben (Marsden) — and, throughout the season, the two become intimate. Jen struggles with her guilt about killing Steve and lying about it to Ben, so she eventually ends their relationship.
Jen and Judy bury Steve’s body in the woods and do their best to cover the murder, but Jen decides to confess after Charlie becomes a prime suspect in Steve’s disappearance.
Before confessing, Jen writes three separate goodbye letters to Judy and her two sons and leaves Judy as their legal guardian. Judy reads her letter but doesn’t get the chance to give Jen’s letters to Charlie and Henry.
Then, Jen visits Detective Ana Perez (Diana-Maria Riva), confesses to murder, and attempts to take her to where Steve’s body is buried.
The two don’t find the body and, after bonding over both having lost a mother, Perez softens. She lets Jen off the hook and tells her to never mention the confession to anyone.
During the finale, Jen and Judy are waiting at a stop sign — one Jen had fought to be placed there earlier in the season — and their car is hit by a drunk driver, who viewers later find out is Ben.
