In the upcoming episode of "Criminal Minds", the BAU finds the biggest case of the season when bodies of two missing persons are found in a car trunk. The BAU suspects that they are victims of human trafficking, so the team searches for a suspected human trafficking ring.
Meanwhile, Aaron Hotchner warns the team of possible changes due to budget cuts as A.J. Cook's Jennifer "JJ" Jareau returns to the FBI. A preview to the season finale gives a teaser to her return by showing a scene where David Rossi talks a woman about giving some thoughts to what the team has discussed.
"Supply & Demand", which is the last episode in season 6, will air Wednesday, May 18 at 9 P.M. ET on CBS.
After her guest star appearance in this finale, A.J. Cook will return as a regular in the seventh season. Shemar Moore has closed a deal to return to the new season with a salary twice bigger than what he got per episode under his old contract, Deadline reports. Thomas Gibson, meanwhile, is still negotiating his return to the crime drama series.
