Derek Morgan: [voiceover] We are tied to the ocean, and when we go back to the sea, whether it is to sail or to watch, we are going back from whence we came. -John F. Kennedy
David, Rossi: Think it's time to rethink Cindi?
Derek Morgan: Rossi, the only connection right now is Charleston. It's weak.
David, Rossi: Victim number five is an African-American woman in her twenties who died in 2004. That's not weak.
David, Rossi: My aunt has spent years obsessing over Cindi's last few hours. She doesn't go out. She doesn't sleep. She forgets to take her medication. It's killing her, Rossi.
David, Rossi: It hasn't been easy for you, either.
Derek Morgan: But everything I've learned as a profiler has taught me that it's not about what I want to be true. It's about what I can prove.
David, Rossi: [voiceover] The sea has never been friendly to man. At most it has been the accomplice of human restlessness. -Joseph Conrad
Penelope Garcia: Enchantress of all things possible, use your imagination.
Aaron Hotchner: Have you nailed down the victimology?
Dr. Spencer Reid: You know, I found a unique evolution, actually. The earliest victims appear to be high-risk. These lesions are consistent with syphilis, most likely a prostitute. This one has severely ground and missing teeth, commonly seen in excessive methamphetamine abuse. And then all of a sudden out of nowhere, a sea change - healthier and stronger victims all the way through to number twelve.
Aaron Hotchner: Lower-risk, harder for him to hunt. What do we know about the first victim?
Dr. Spencer Reid: You know, that one's tough. He or she has been in the water so long, they're mostly bone fragments. I can attempt to reconstruct...
Aaron Hotchner: You've got three hours.
Dr. Spencer Reid: I can do it in two.
Aaron Hotchner: Make it one.
David, Rossi: Some years back, Morgan's cousin fled a stalker. She made it to South Carolina. She was never seen or heard from again.
Ashley Seaver: Was it the stalker?
David, Rossi: He killed himself two weeks later, so we never found out for sure. But Morgan's profile led straight to him. So whenever unidentified female remains turn up, he gets that call.
Yvonne Burns: Did you find her?
Derek Morgan: No, Auntie.
Yvonne Burns: I'm never gonna know, am I?
Derek Morgan: He picked out her picture.
Yvonne Burns: He did?... Thank you. Thank you... Thank you.
Dr. Spencer Reid: I don't think this was written under duress. You said Dr. Cormick wasn't taking medication for Parkinson's, right? Look at her handwriting. No indication of tremors or shaking. There's a drug called trilamide. In minute doses it treats Parkinson's, but its main use is for seasickness.
David, Rossi: Something a fisherman would have access to.
Derek Morgan: And criminals in South America. Intel reports say they figured out a high dose makes a victim totally compliant.
Dr. Spencer Reid: Yeah, they slip it in your drink or blow the powder in your face and nasodermal absorption's almost immediate. You're instantaneously susceptible to any suggestion. There have been reports of locals letting thugs into their apartments to rob them, even helping them load the getaway trucks.
Blake Wells: [Morgan shows Cindi's photo] I didn't dump her there, did I? She means something to you, doesn't she?
Derek Morgan: They're all special to me, Blake. If you can't remember her, we can just move on.
Blake Wells: I do remember her. You want to know, Agent Morgan, who she cried out for right before I made her slice her own throat?
Derek Morgan: Go ahead. Tell me.
Blake Wells: You. She cried out for you. Where were you when she bled out on the floor of my boat?
Derek Morgan: You're a sick son of a bitch. But you didn't kill her.
Blake Wells: I did kill her.
Derek Morgan: No. You didn't. And I was very clear about the rules. Deal's off.
[Morgan leaves the room]
Blake Wells: I did kill her. You said you wanted to learn from me, and now you won't listen! Hey, come back here! Agent Morgan! I did kill her!
David, Rossi: How'd you know?
Derek Morgan: He knows his victims' names. He didn't know Cindi's.
Blake Wells: Agent Morgan, you get back here!
Dr. Spencer Reid: The wounds on the thigh show hesitation marks. An unsub this experienced wouldn't display that.
Derek Morgan: I don't think the unsub did. The angle indicates left-handed dominance. The file says this guy was left-handed, too.
Dr. Spencer Reid: You know, if he'd been given trilamide, the unsub could have forced him to cut himself. It makes sense for a sadist with abandonment issues, but wouldn't he finish the job?
Derek Morgan: The victim must have gotten a chance to escape and took it.
Dr. Spencer Reid: But how? The trilamide kept him compliant enough to hurt himself. It overcame his self-preservation instinct.
Derek Morgan: Well, then another instinct must have been stronger.
Dr. Spencer Reid: Like what?
Derek Morgan: A protective one. This guy was mentally and physically compromised, but he still went after the unsub with everything he had.
Dr. Spencer Reid: Who would he fight that hard for?
[cut to Morgan on the phone with Garcia]
Derek Morgan: A child, Garcia. Search nationwide missing persons reports for men traveling with their kids.
Penelope Garcia: Am I looking for a son or daughter?
Derek Morgan: We don't know yet.
Penelope Garcia: No, no, I'm sorry, honey. No dice. Hey, what if they're not reported as missing yet?
Derek Morgan: Yeah, of course not. When the unsub met them, they were starting over. All right, baby girl, new deal. USPS changes of address notices, people moving into Florida and South Carolina.
Penelope Garcia: Done.
Derek Morgan: All right, eliminate women, wives, couples. Narrow it down to men only.
Penelope Garcia: So... so we're thinking divorced dad here, right?
Derek Morgan: Yeah, but not just any divorced dad. This guy wants as much distance between his son and his ex-wife as possible. So look for custody disputes, injunctions, allegations. The messier, the better, Garcia.
Derek Morgan: Drop it. Drop the knife.
Blake Wells: Stand back. Stand back!
Derek Morgan: Okay, okay. I'm gonna put this away, all right? I just want to talk to you. Come on, man. Look at James. He's just a kid. Blake, you don't hurt kids. You're not that guy.
Blake Wells: You have no idea who I am.
Derek Morgan: I know that you're a smart man. You had a long run at killing under the radar. But I also know that we can learn a lot from a man like you. See, studying men like you is my responsibility. And I'm telling you, if you let James go, we can be a part of your life. We won't abandon you, Blake.
Blake Wells: What makes you think I want to teach you?
Derek Morgan: Look at your alternative, man. My guys are ready. They will take the shot and they will kill you. What happens after that, Blake? Do you really think you're gonna get to see your mom again? Or maybe it'll just be cold, dark, empty. Like the water where you put your dad. It's your choice, man.
[Blake drops the knife]
