"Criminal Minds" will return to CBS this Wednesday, Dec. 11 with an episode that addresses the modern day phenomena of bullying.

In the upcoming episode, Blake, her father, a retired police captain, and her brother, a detective, reunite under intense circumstances as they must work together on a murder investigation, according to a press release on SpoilerTV.com.

The official "Criminal Minds" Twitter account released a cheat tweet about the upcoming episode stating, " It's no happy reunion when Blake works w/her police cap't dad & detective bro in KC on #CriminalMinds 12/11, 9pm."

More than likely, "Bully" will be the "fall finale" since no information has been released concerning a follow up episode on December 16 and it is highly unlikely that the show would air a new episode two days before Christmas.

In addition, The Hollywood Reporter exclusively reports that actor Paulo Costanzo will appear in the 11th episode of the season. The "Royal Pains" star is leaving the Hamptons and has booked a guest-starring gig on the veteran CBS police procedural series. He will appear an old friend from Garcia's (Kirsten Vangsness) troubled past who she hasn't seen since she joined the BAU.

Fans of "Criminal Minds" can also look forward to the return of former regular Paget Brewster who is set to star in its 200th-episode milestone.

The "Bully" episode of "Criminal Minds" airs on Wednesday, Dec. 11 at 9 p.m. on CBS.
