Jen goes through it in season two. Not only is she still dealing with the investigation into Ted's death, but she also has to contend with killing Steve (which she tells Judy was in self-defence, but definitely wasn't). By episode ten, Jen has been completely overwhelmed by all the secrets and lies she's embroiled in to keep her out of jail. She decides to confess to Detective Perez after writing letters to Judy, Charlie, and Henry explaining why she left and dubbing the other woman her children's legal guardian.
But when Jen and Detective Perez get to the woods, she can't find where she and Judy buried Steve's body. As the two drive away, they bond over the shared loss of their mothers, and Detective Perez is compelled to not be a cop for once. She tells Jen she won't charge her for Steve's murder and that they'll never talk about "what we never found in the woods today" ever again. Burdens relieved, Jen returns to group therapy to talk about the loss of her mother and her need to forgive herself for how she acted and how she felt, the finale's first full-circle moment from the pilot episode.
