Loyalties, friendships and sanity are tested in this season of "Criminal Minds." Dr.Spencer Reid (Matthew Grey Grubler) is now being put through his greatest of all tribulations, on top of his ongoing struggles dealing with his mother. SSA Jennifer Jeraue (AJ Cook) is becoming very aware the toll the job is taking on her personal life, making her question if the BAU is truly for her. SSA Rossi (Joe Mantegna) is forced once again to step up and lead the BAU, while SSA Hotchner (Thomas Gibson) is on a temporary work assignment. As Dr. Lewis (Aisha Tyler) and Agent Aleverez (Adam Rodriguez) adjust to life with the BAU, Penelope Garcia (Kirsten Vangsness) is still dealing with the absence of Derek Morgan (Shamar Moore), which greatly changes her demeanor this season.
