"Your sure?" Hotch exclaimed as he held the phone close to his ear. "Okay. Hurry back. Be careful."

"What's wrong?" Meghan asked, peering out from behind her computer screen. "I- I mean- not to be nosey. You know what, forget I said anything." She waved her hand and leaned back, shaking her head.

"Hotch?" Morgan looked at him after he stopped laughing.

"The victims were-" He paused to close the door. "The victims died from inhalation and absorption of sarin gas."

Rossi's eyebrows shot up as Morgan just frowned. "Sarin gas. That's the nerve gas that was declared a W.M.D."

"That means weapon of mass destruction." Morgan leaned towards Meghan, smirking.

She rolled her eyes and placed a hand on her heart dramatically. "Really? Wow I was so off." She shoved him away. "So are they okay?"

"You mean is Spence okay?" Morgan teased.

"That's enough Morgan." Hotchs voice rang out. "We don't have time for nonsense. If this unsub has his hands on a W.M.D then we're all in trouble."

"Hey." Prentiss called, walking in. "I heard. We didn't profile for a terrorist."

"We should take the necklace to the forensic team now. See if there are any prints." Rossi suggested.

"Good idea. Meghan could you grab it please." Hotch asked.

She nodded and made her way over to the box, frowning at Prentiss' face. "You okay Emily? You look flushed."

"Still not feeling good?" Morgan asked.

"I- I'm fine." She rubbed her sweaty palms on her black pantsuit, swallowing hard as her fingers brushed against the necklace bag in her pocket.

"Uh- Hotch. Is there another box." Meghan dug quickly yet carefully through the cardboard box.

"No. Why?"

"Well, the necklace isn't in here."

"What?" Rossi hoped up and joined her in her search. "She's right. It's gone. Who was suppose to put it in here."

"I did. I'm sure I did." Morgan raised his hand slightly.

"Are you positive?" Meghan quirked one eyebrow.

"Yes." Morgan growled back. "I'm positive."

Prentiss backed up lightly until her back was against the cool door. She let her head fall back, pressing her palm to flushed forehead.

"Prentiss?" Hotch stepped closer to her. "Do you know something about this?"

Her eyes widened and she shook her head, shocked at how nervous she was. "I- no."
