[Warning: The following story contains spoilers about Wednesday's episode of Criminal Minds. Read at your own risk.]That sound you hear is baby girls crying everywhere.After 11 years and (probably) 103 broken doors and 214 tackles, Shemar Moore exited Criminal Minds on Wednesday's episode.Directed Moore's "little brother" Matthew Gray Gubler, and written by his "baby girl" Kirsten Vangsness and showrunner Erica Messer, the episode quickly reveals the aftermath of last week's shooting: Morgan's (Moore) pregnant wife Savannah (Rochelle Aytes) was shot, but she and their baby survive. It's all hands on deck once again to catch the unsub -- Chazz Montolo (Lance Henriksen), the father of Dirty Dozen hit man Giuseppe Montolo -- minus one. Hotch (Thomas Gibson) removes Morgan from the case because it's too personal and he doesn't want Morgan's family to suffer the same fate his did after his tango with The Reaper (RIP Haley). Obviously, that doesn't sit well with Morgan. But after getting some hints from Reid (Gubler) and an actual message from Montolo from JJ (A.J. Cook), who doesn't agree with Hotch's call, Morgan goes rogue and heads to one of his renovated houses (callback!), where he finds Montolo, who (wrongly) believes Morgan killed his son earlier this season.Montolo sadistically holds Morgan at gunpoint with only two bullets loaded. "If this is how it ends, it's meant to be," he tearfully tells the BAU over the phone as Montolo clicks through the empty chambers. "Promise me you'll look after Savannah and my baby." But he tackles Montolo and refuses to shoot him unarmed despite Montolo's taunts. After the BAU busts in and arrests Montolo, Morgan makes it back to the hospital in time for the birth of his son, Hank Spencer (!) Morgan. "Hotch, I get it," he says. "I never knew that 6 pounds, 1 ounce could knock me out."As Morgan takes stock of the highs (marriage, baby) and lows (oh, you know, being kidnapped, tortured and burned) of the past six months, and his new priorities, everyone knows what's coming, even though it's never explicitly said. "I don't want you to stay," Reid says. "Because I know why you're leaving and I couldn't be happier for you." And so, after some emotional, heartfelt "this isn't goodbye" goodbyes with everyone -- "You will always be my original baby girl," he tells Garcia (Vangsness) -- Morgan leaves behind his BAU family for his new real one.TVGuide.com chatted with Moore about his exit, why this episode is his proudest moment on the show, the birth of "baby girl" and more.
