Detective Perez has to deal with a lot of Jen and Judy's shenanigans, but season two takes the cake. After Judy confessed to Ted's hit and run in season one, Perez finds her living with Jen again in season two. She continues keeping an eye on them while dealing with the FBI looking for Steve. Then, her ex-girlfriend finds a new relationship with Judy, who Perez has no love for. By the season finale, we're not shocked to find her crying and emotional over the way her life has taken her recently.
When Jen confesses to killing Steve and attempts to show the detective his burial place, the two manage to bond over their shared loss of a mother, and Perez is moved to ensure that Charlie and Henry don't lose their mother as well. She tells Jen she won't charge her and that they'll never talk about "what we never found in the woods" ever again. It's well-intentioned, but then, we not only see the dog that Jen and Perez ran in to start digging around Steve's burial site, but we see Ben receive a phone call that causes him to tear out of his home. It looks like Perez and Jen won't be able to keep what they never found a secret for very long.
