Catching the skeleton head her friend threw at her, Emily let out a laugh, having it drop down to her desk. "Gross," she chuckled, watching Derek do his best to catch his breath again. "What has you so creeped out?"

The other agent shook his head. "I'm not into the whole scary thing. Don't we get enough of that?" Leaning back in his chair, the bald man gave his friend a wink. "The way to spend Halloween is to have some wine, put on a movie and sit back with a little Halloween honey."

"Ew," Emily snorted, seeing Reid's confusion as he sat down at his desk. "Halloween honey? Now I'm creeped out."

"Have you two met Agent Rossi yet?"

Turning back to the genius across from her the brunette nodded. "He seemed really nice," she smiled, getting her file together for Hotch. "I met him over at the kitchenette yesterday morning, and he met Penelope. He seemed a little confused by her," the FBI agent laughed.

Derek sighed. "He seemed a little uptight."

"He's sixty-two years old," Reid pointed out, "and a lot's changed since he and Gideon started this unit. I'm sure he has some opinions on everything."

Emily looked up from the papers she was organizing. "You didn't get to meet him yet, did you?" She knew he was still getting over Gideon's quick departure so a change of subject was best. "I know you have all of his books."

The younger man was quick to nod his head, slipping off his mask and sitting down at his desk. "Every one he's ever written. I've read How to Catch A Killer by David Rossi a record four hundred times."

"Four hundred?"

All three BAU agents stood from their desks to greet the newest member of their team.

The previously retired FBI agent smiled to the agent in a sweater vest, letting Hotch leave them for a moment to get Penelope from the kitchenette. "I've met some really crazy fans but I've ever met one with that much time on their hands."

Reid shook his head. "It only takes me fourteen minutes to read through it."

The goateed man stared blankly at the genius.

"He's a genius with an eidetic memory," Emily supplied, laughing along with Derek as they tried to get the older man to stop staring. "Don't worry, you'll get used to it."

"Dave, you've met Penelope."

The blond woman was quick to raise a hand and wave at the older man. "Nice to meet you again, Agent Rossi. Can I do anything for you? Get you some coffee?" she asked with a smile. "A neck pillow for when the day feels too long? Can I help decorate your office?"

The writer in the room tried for a smile. "I'm alright for now, thank you." He watched her walk away before he turned to face the others in the bullpen. "I thought you said there were six of you."

"Jennifer Jareau is our media liaison," Hotch nodded, leading his old friend away from the desks and up toward his office. "She doesn't call us in for a briefing until ten, but today she's just dealing with paperwork."

Watching the two older men walk away, Reid held a smile on his face.

"You did good," Emily nodded to him, knowing he was waiting for a confirmation. Smiling until he sat down and turned his head, the agent looked back to her friend to her right. "How about now?"

"Still uptight," Derek answered.

Looking over to the older woman who sat next to him, Derek found himself grinning. "Wore a skirt today, huh Princess?" When she turned to look to him, he saw her grimace. "How long are those legs?"

"Long enough to reach out and put my heel up your ass."

Derek's face fell. "Harsh, Princess?"

Emily grinned at the look on his face before going back to her files, her heel poking at the silky skin of her leg as she crossed them in her seat. "Do you guys want lunch in an hour?"

"You buying?"

The ambassador's daughter frowned. "I'll drive, you buy."

"Emily?"

Spinning in her seat, one of the newest members to the team smiled to their resident liaison. "Hey JJ," she smiled. "Hey, do you want to come to lunch later? Derek said he was buying."

The darker agent threw up his hands. "I did not!"

JJ's lips thinned, watching the interaction with narrow eyes. "Emily, I need you for a minute."

Emily frowned, noticing the demeanor of the younger woman. Standing from her seat, she made her way over to JJ near the BAU entrance doors. "What's the matter?"

"I got a call for you." She gestured out the doors and toward her office. "It's your mother."

Immediately the ambassador's daughter raced by her new friend and out the glass doors. She slid past a few agents talking near JJ's office door before racing inside, picking up the phone and taking it off hold. "Mother?"

"I'm so sorry, Emily."
