The team finally lands in Las Vegas, Nevada. Immediately, they head off to get started.

Morgan looks around the alley, the same way he had years ago when they worked the Shelby Scott case. Prentiss checks the blood spatter and stands in the spot Wendy Collins stood right before she was shot.

"Okay, so this must be a female. The lipstick, the need to perfect…"

"I'm the UnSub, your Wendy." Morgan says. "I used a .22, chose a secluded alley, but what am I accomplishing by killing you?"

"Well, Shelby Scott thought she was helping women by killing men. Maybe this UnSub thinks killing these women will help someone." Prentiss thinks.

"Maybe they did something or acted in some way to remind the UnSub of someone else."

"If it was that, why would they imitate Shelby Scott? Why the kiss and the notes?"

"Shelby Scott's murders were publicized. Maybe the UnSub was fascinated by it and wanted to prove her own smarts."

"What if the UnSub knew Shelby and wanted to pass her up?" Prentiss suggests, her dark hair whipping in the wind.

"Typical female logic," Morgan taunts. "I guess when Reid figures out the code we'll understand it."

"Is the UnSub organized or messy?" Rossi asks, looking at the splattered blood.

"The UnSub wants attention because of the note. Didn't leave anything behind. I guess she's organized."

"Are we sure it's a woman?"

"The lipstick, girly writing, and mimicking a female murderer. It sure seems that way." Hotch says.

"Or it's a smart man, trying to confuse the police."

"That's highly unlikely." Hotch says.

"Just trying my theories." Rossi says, knowing how ridiculous he statement was.

At the station, Spencer pins up the pictures of Wendy Collins and Chelsea Bryant. Something nags in his head and he forces himself to look closer.

"J.J., these girls look like Shelby Scott." Spencer says suddenly. J.J. swings towards him and squints. She looks through a pile for Shelby's photo and compares.

"Not really…" She says skeptically.

"Small things. Wendy's facial structure, Chelsea's eyes have the same shape, along with her lips." Spencer says, his mind flashing back to when Shelby Scott held a gun to him. He could see it clearly.

He draws a profile starter and adds things: smart, organized, 20s-30s, female.

"I really wish she just gave us a note the normal way." J.J. says, staring down at the numbers.

He shakes his head. "This is more than what we're seeing." He says to himself. J.J. shrugs, completely lost.

"She's killing women like Shelby Scott. What if she was a past victim's family member, wanting revenge on Shelby?" Spencer says.

J.J. doesn't say anything, thinking it over first. Finally, she answers, "We need to figure out the code first."

Spencer nods a little disappointed and sits down in his comfortable seat. He tries numbering Spanish alphabet, and strikes out again. He even tries the ancient Roman alphabet. Still, nothing.

The others all come back, frustrated.

"Do you think you can figure out the code?" Hotch asks.
"I don't know. It could literally be anything."

Shaking his head, he tries the German alphabet as J.J. tells the team of Spencer's earlier theory.

While everyone mulls it over, Spencer's phone rings. He flips it open, not bothering to check the caller ID.

"Spencer?" Nathalie's voice says panicked on the other end.

"What's wrong?" He answers, her having his full attention.

"Jessica. I can't find her!"

"What do you mean?" Spencer asks, his heart race rising.

"She was in her room! Now she's…just…not there!" Nathalie says, close to tears. Jamie and I have tried calling, and I called the police to file a missing persons.

"She could have just snuck out." Spencer reasons.

"I just don't know!" Now, Nathalie was in tears, and Spencer was in full panic mode.

"How did she seem this morning?"

"Fine. Sulky and moody, the usual."

Unsure of what to say, he flips his phone shut. He couldn't possibly bear listening to anymore. He immediately tries Jess's phone, but he gets the voicemail.

"Jess, please let us know if you're alright." He begs. He shuts it and looks up at his team.

"What's going on?" Prentiss asks.

"Jessica is gone."
