Through the Looking Glass (S08E03)

When one family turns up dead and another goes missing, the BAU attempts to find a link between the cases in order to determine who is behind the kidnappings and murders. As our team searches for relevant family history that might identify the UnSub, the missing family is forced to face their own inadequacies at the hands of their captor. After being locked in a secure replica of a suburban home, members of the captured household are made to reveal their deepest secrets to each other as the UnSub punishes them for failing to be the perfect family.
