Serenity Tsukino sighed as she stood in the elevator of the FBI headquarters in Quantico with a box in her hands. She was heading to the floor that held the Behavioral Analysis Unit of the FBI. Her cousins Penelope and JJ worked there. They had both been trying to get her to visit them at work one day and now she was finally doing it. She just wished it wasn't going to be of something that for them would be work related. Her blond hair was down, hanging almost to her ankles and she had a pair of sunglasses on. Finally the elevator had reached her floor and she stepped off and through the doors leading to the bullpen. She looked around and easily pinpointed JJ at her desk.

Serenity smiled and walked over, looking at the pictures of JJ's husband and son. "I thought I was your favorite cousin and I don't even get a picture on your desk. I'm hurt." she teased.

JJ looked up in confusion before grinning as she recognized Serenity's hair. She stood and hugged her. "Well sorry that all the pics i have are the ones the media took." she teased back.

"I'll have to rectify that soon then." Serenity grinned as she stepped back.

"So what brings you here? I thought you were on tour?" JJ inquired.

Serenity sighed. "I am on tour. I've got rehearsal tonight actually. I wish this truly was just a social visit but I need help. From you and Pene and your team." She held out the box to JJ.

JJ frowned and took the box. "Before I look at this, did you try going to the police?"

Serenity shook her head. "When I got the first, I briefly considered it but shook it off as just a random moment of someone trying to spook me for fun. But when the second set came in, I knew there was no point in going to police. I remembered that you told me a case automatically becomes federal territory if state lines are crossed. The second set and the others since are from different states. I've got a stalker, JJ. One who's also a serial killer." She gestured for the other blond to look in the box.

JJ set the box on her desk and opened it to find multiple small envelopes within. She grabbed a pair of gloves and pulled them on before peeking in the envelopes and seeing notes with photos of murdered women who all, like Serenity, had blonde hair and blue eyes.

"What you got there JJ?" Aaron Hotchner asked as he walked over. He then saw Serenity. "SSA Hotchner. And you are?" He held a hand out to Serenity.

"Serenity Tsukino." She shook his hand. "Pleasure to meet you. JJ is one of my cousins."

"Hotch...the contents of this box Serenity brought in is looking to be our next case. And I'm not just saying it because Serenity is connected as these things were sent directly to her." JJ spoke up grimly. "Just need to have Penelope officially run the images for matches so we can get jurisdiction properly." She looked to Serenity. "I'll need the list of dates of when you were in the cities these happened in or were sent to you in. It'll help Penelope narrow things down."

Serenity nodded and began writing down the list. "I always got them at the hotels I was staying at as I was checking out the day after my concert. But I usually make it into town a couple days before the concert to allow for at least one rehearsal."

"How long will you be in town for your concert this time?" JJ asked.

"A week. I have two shows this time. Hopefully it'll give you guys more than enough time to catch this guy." Serenity answered.

"Wait, concerts? What sort of performances do you do?" Aaron asked.

"Oh. Right..Im a singer. I go by the stage name, Lunara." Serenity explained. She then looked to JJ. "Can we go see Pene now?"

JJ chuckled as she grabbed the box. "Yeah sure." She looked to Aaron. "Hotch, Garcia and I will be in to talk to the team in about thirty minutes."

Aaron nodded. "Go on ahead. I'll spread the word around."

JJ nodded and led Serenity back to Penelope's office. "I know you likely have your own bodyguard, but it's highly likely that you'll be given extra protective detail until this guy is found."

"I understand. Especially since this stalker seems so obsessed with me. Just my coming here might've essentially increased the danger towards me." Serenity spoke grimly. "If it means getting a little extra protection until this guy is stopped, then so be it."

"What's this about extra protection?" Asked Derek Morgan as he walked towards them, having just left Penelope's office himself.

"We got a case Morgan." JJ spoke up. "High priority on this one. Meet my cousin, Serenity also known as the singer Lunara." JJ grinned. "Serenity, this is Derek Morgan, another member of the team."

"You forgot the SSA, JJ." Derek grinned as he held his hand out to Serenity. "So you're the infamous Lunara that Penelope was trying to convince me to go see. She'd mentioned something about a plan to surprise you backstage. A pleasure to meet you."

Serenity giggled. "Well she wouldn't have had a problem doing that. My bodyguards have orders to let Penelope and JJ back to see me backstage. Pene is my other cousin. It's a pleasure to meet you too." She placed her hand in his and shook it.

Before Serenity could pull her hand away, Derek lifted it and gently kissed it, causing her to blush. He let her hand go while giving her a flirty smirk.

"We were just heading back to see Penelope about the case. We'll all meet in the conference room soon for a debrief." JJ explained.

Derek nodded. "Well then I won't hold you up. See you ladies soon."
