A BAU team member’s family “reunion” quickly escalates into an UnSub situation, as seen in this exclusive sneak peek from Wednesday’s Criminal Minds (CBS, 9/8c).

In “Mirror Image,” which was directed by cast member Joe Mantegna, Dr. Tara Lewis (played by Aisha Tyler) gets a visit from her brother Gabriel. Thing is, Tara of course knows her brother, and this stranger (guest star Alimi Ballard) ain’t him! And yet, this “Gabriel” knows everything about Tara and her (their?) family.

Confusing matters even more, Tara is unable to make contact with the “real” Gabriel….

In the clip above, Rossi and Prentiss pull Dr. Lewis in for a meeting, to weigh in on her sibling mystery — and how it might tie into Hotch entering WITSEC.
