Blair and Serena walked down the hallway and as usual, everyone cleared the way to make room for them. Chuck had called them to meet up and they walked faster than usual, expecting new from Chuck's PI. They turned a sharp corner and bumped hard into an unsuspecting freshman

"Excuse you!" Blair could've walked around him but she stood her ground. "Move."

The boy looked at her. "Uh…

Serena grabbed Blair's arm and pulled her away. "B, let's focus on Chuck."

Blair let loud a loud scoff. "How dare he? Obviously he doesn't know who rules this school. But I'll deal with him later. Chuck, there you are!"

Serena frowned when he saw the expression on Chuck's face.

Chuck cleared his throat before speaking. "Nothing. Not even a number, I don't know it's possible. It's like an automated machine is sending us these messages."

Blair frowned. "Maybe they're using the internet to get to our phones."

Chuck nodded. "That's what it appears to be. But it also appears as if it's somewhere outside the country so we don't get an IP address or anything."

Serena leaned on Nate's shoulder. "How is that possible?"

Nate rubbed his eyes lazily. "We don't need a PI to figure out who's sending us these messages. It's Georgina. She's trying to mess with us."

Blair shot him a dirty look. "Are you an idiot? You know as well as I do that she's dead. Do I need to remind you that we…"

Chuck stepped in front of Blair. "Enough. I'm going to class."

They all exchanged looks. They'd never heard Chuck Bass say anything of that sort. Serena straightened up and linked her arm with Blair's. "Come on, B. Let's go."

…

"Serena! I'm here! What's going on?" Nate was out of breath from running.

"Bathroom!"

Nate took long steps towards the bathroom where Serena stood brushing her hair. "It sounded urgent on the phone. I came as fast as I could."

"I just wanted to see you, that's all."

Nate let out a frustrated sigh and went back to her room. He sat on her bed. "Are you serious? You told me you needed me and that I had to come ASAP…"

"Don't be mad, Natie. I was just bored."

Nate rolled his eyes. "Well I'm here. What do you want?"

Serena sat on his lap and smiled. "What do I want?" She leaned over and whispered playfully in his ear.

Nate shook his head softly. "You need to stop doing that."

She looked at him innocently.

He got up. "I'm gonna go."

"Wait, I wanted to watch a movie or something."

Nate turned to her. His patience was wearing thin. "It's late."

Serena frowned. "Nate…"

"I'll see you tomorrow." Nate turned to leave when he heard both his and Serena's phone chime. He fished his phone out of the pocket and read: Knock knock, S xoxo.

Serena looked up from her phone just as the doorbell rang. Nate walked ahead of her to find a thin box on the floor. Nate picked it up and handed it to Serena. She had no idea what could possible be in there. She ripped through the wrapper quickly and opened the box to find a single piece of paper.

Nate peeked over her shoulder. "What is it?"

Serena crumbled up the piece of paper before he could see it. "Nothing."

Nate looked unconvinced.

Serena turned away. "It's nothing. I'm going to bed."

…

Serena frowned as she watched Nate with another girl on his lap. She leaned towards Chuck. "I'm hotter than her, right?"

Chuck looked over and studied her for a few seconds. "Yeah. Substantially."

"So why is he over there?"

"Why do you suddenly want Nate so badly?"

Serena felt her face get hot. "What are you talking about? I was just saying…"

Chuck shook his head. "Always wanting what you can't have."

Serena frowned. I can't have Nate? "Thanks for the analysis. Maybe I should pay you instead of my actual therapist. And who says I can't have him?"

"You're awfully confident."

She shrugged and took another sip of her drink.

Chuck raised his glass to hers. Serena and Nate's relationship upset him more than it amused him. As hot as Serena was, Nate deserved better. He gave her his signature smirk. "He deserves better than you."

Serena looked down. He was right.

He pointed to her chest. "Someone not so…damaged."

She looked at him. "The pot calling the kettle black. Wonderful." She set her drink down and walked quickly away.

Nate walked over to Chuck. "What happened?"

Chuck shrugged. "I told her she didn't deserve you."

Nate shook his head. "Stop picking fights with Serena."

"That's not the thing that upset her."

"She's one of your best friends."

"Exactly. I tell her these things because I care."

"Just play nice." He looked over at the girl waiting for him. "Can I use your room for a bit? I have company."

Chuck nodded. "But hurry, I'm having company soon too."

…

"I didn't mean to upset you the other night."

Serena looked at Chuck. "Is this your way of apologizing?"

Chuck shrugged, he never really apologized. "I guess so."

"You were right. I think the same thing."

Chuck frowned. "I shouldn't have said anything."

Serena wanted to change the subject. "So am I the only one who's received a package from that creep?"

Chuck nodded. "I haven't gotten anything. But we're all spending the night at Blair's so you'll be safe."

"Okay. Let's go."

Serena was almost asleep when she heard footsteps in the hall. She got up slowly and followed them. "Nate? B? Chuck?"

She heard her phone chime and went back into the room to check her message: Boo! Look around, S. Nowhere is safe, xoxo.

Serena got the feeling that someone was watching her. She tiptoed to the next room and opened the door softly.

Nate sat up when he heard the door close. "Serena?"

She walked over to the bed. "Can I sleep here? Please?"

Nate nodded lazily and scooted over. He waited until she climbed in to pull the blanket over her. "You're shaking. What's wrong?"

Serena buried her face in his neck and he wrapped his strong arms around her. "I just want to sleep."

…

It was Saturday night and they were all staying in. Nate didn't get much sleep, he was too freaked out by how freaked out Serena was.

Serena lay next to Nate watching him sleep. The harder she tried to think of nothing the more she thought about everything. She heard her phone vibrate and snatched it off the nightstand before it could wake Nate up.

She looked down at her phone and read: X marks the spot! Want answers? Come alone. Xoxo.

Serena got off the bed carefully and went to he next room to pull on clothes and grabbed the crumbled sheet of paper from her purse She grabbed her phone and walked down the stairs quickly and quietly. She ran across the street and across the park towards the duck pond. She used her phone as a flashlight and walked around the patch of grass until she saw a small red flag over a patch that was freshly dug up.

She used her hands and desperately dug up that patch of dirt until she found a box with Christmas wrapping paper on it. She opened the box and heard a small popping noise and caught only a glimpse of something shiny before she was covered is something warm and sticky. She looked down at her hands and she was dripping in blood.

She grabbed her phone and her box and turned to run back to Blair's penthouse when she felt a light shine in her face. "Freeze!"
