This week's Criminal Minds featured the discovery of bodies at the bottom of the great "Big Sea," with one set of remains potentially hitting close to home for Morgan.

When Morgan's aunt believed that her daughter (therefore Morgan's cousin) may be among the victims, the case obviously took on new meaning for the BAU member.

Shemar Moore delivered a typically strong performance in a typically strong episode of the CBS procedural that conjured up vivid images of Season 2 of Dexter.

In this case, though, the mass murderer was much less charming.

Based on the watery graveyard's location, the team assumes the UnSub could be local, and based on some of the skeletal discoveries, may even be a fisherman.

Rather than becoming emboldened and pushing the envelope with each kill, Reid believes the assailant is actually targeting lower-risk victims as he progresses.

After a fun exchange with Reid about how long it will take to reconstruct the first victims, Hotch speaks to the press, asking for help identifying missing persons.

Morgan's aunt is one such person with a missing loved one.

You had the sense early that Morgan wasn't telling Yvonne the whole story. Rossi tells Seaver that Morgan's cousin escaped a stalker and was never heard from.

Hotch believes that based on the remains, there is an overkill aspect to one of the early murders, stemming from a troubled personal relationship or several.

Clearly whoever's doing this is one sadistic individual, as evidenced by the chilling shot of the powder blown into the victim's face until his struggling ceases.

Reid discovers a substance that can be used to control someone when taken in high enough quantities, while we see more evidence of the UnSub at "work."

Meanwhile, we get a little back story on Morgan's family and it doesn't look good for Cindy, as the victims are all trying to start over, looking for a fresh start.

On the UnSub's boat, Gary tries to escape, but fails. When his body turns up, the team notes his ability to overcome the drug - and that his son is out there.

The UnSub still has James under his control. Then the breakthrough on Cindy. Yvonne remembers that she flew as an unaccompanied minor back in the day.

They've finally got their man in Blake Wells, who nabs his victims in transit. Just as Blake tells James about his father's abuse, Morgan arrives on the scene.

Somehow, Morgan is able to talk him into dropping the knife, but the most powerful scene of the entire episode came during Wells' subsequent interrogation.

When Morgan shows him Cindy's picture, the UnSub senses vulnerability and claims she cried for Morgan before her throat was sliced. Morgan knows that's a lie.

The killer didn't know Cindy's name, but he knew those of the other victims. But Morgan lies to his aunt to give her closure. A difficult decision - but the right one?

Next week, on the sixth season finale, the bodies of two missing people are found in a car trunk, and the BAU suspects an interstate human trafficking ring is at work.

Also, Hotch warns the team of possible changes, and they are surprised when a beloved team member returns for good - none other than A.J. Cook as the beloved J.J.
