The youngest member of an orphaned clan kills to keep his dysfunctional family together. The first murder occurs when the young man kills the boyfriend his sister is considering marrying. Her marriage would result in her leaving the family and that would be unacceptable. Sam profiles that the killer is someone who has felt loss and who is desperately trying to hold on to something he values. The VCTF eventually discover this decidedly unconventional family and at first, mistakenly believe the physically abusive eldest brother is the killer. Sam soon realizes, however, that there is another, more emotionally immature force at work. Meanwhile, Bailey realizes his ex-wife, Janet, is seriously involved and considering remarriage. Also, Chloe is upset when Sam invites her new boyfriend, Paul, over for Christmas.
