Penelope didn't know what to do. She knew that Lisa hadn't booked a flight back to D.C. That she might not ever book a flight back. She couldn't believe it. She didn't want to believe it. Spencer was like a little brother to Penelope and the thought of him being hurt like this, being left like this, it made her insides boil. She couldn't sit back and watch this happen. She just couldn't. She picked up the phone and dialed Lisa's number.

"Hi, you've reached Lisa, leave a message. Beep."

"There had better be a good explanation as to why your name is not on any flight lists for tomorrow. Spencer thinks you're coming back tomorrow and if you're not coming I need to know. I swear to God if you hurt my baby boy I will make sure you regret it for the rest of your life."

She hung up and stared at the phone. She was scared and angry but most of all she just wanted answers, answers for Spencer and also for herself. This wasn't like Lisa. Yes she could have her flighty moments, forget a lunch meeting every now and then, or decide to go somewhere else on a whim. It was what made Lisa, Lisa, but this this was wrong. Lisa had been so excited to marry Spencer it didn't seem right that she would leave like this.
When Penelope woke up in the morning she still hadn't got a response from Lisa. For the rest of the day she kept checking her messages as well as the Las Vegas flight database every few minutes. It was difficult to concentrate. By 11:00 Penelope had decided that if she didn't hear from Lisa soon, she was telling Spencer what she knew, no matter how much it might hurt him to hear it, it was better than waiting around. It had to be.
At noon Penelope couldn't wait any longer. She left her cave and slowly walked out to Spencer's desk, planning out what she was going to say on the way there. She stopped mid-stride though when the elevator at the end of the hall opened up and Lisa stepped out into the hallway.

"What the hell are you doing here?" she said before she could stop herself.

"Nice to see you too Penny." Lisa said.

"How are you here right now?" Penelope asked, unable to get off of the topic.

"I took the elevator." Lisa said motioning to the machine behind her.

"But you were never on a flight."

Lisa's eyes went wide. "You checked on that?"

"Didn't you get my message?" Penelope asked.

"No, my phone charger was in my checked bag, my phone hasn't worked since Tuesday. I've been using Rachel's. What did it say?"

"I asked why your name wasn't on any flight manifests."

Lisa looked around and pulled Penelope off to the side. "I didn't fly back." She admitted.

"Then how did you get here?"

"I drove, Rachel came with me, please don't tell Spencer." Lisa asked looking panicked.

"Why don't you want him to know you drove?" Penelope asked.

"It's part of a surprise for him." Lisa said.

"What surprise?"

"You'll find out" Lisa said with a smile, "Just promise you won't tell him."

"Okay I promise." Penelope said. Seeing Lisa back, with an explanation, relieved Penelope, now though she felt bad about how angry she had been in her message to Lisa. "As long as you promise to delete the message I left you."

"Deal." Lisa smiled.

"It's good to see you back." Penelope said before grabbing Lisa and hugging her.

Lisa smiled and hugged her back as the two walked into the bull pen together and over to Spencer's desk.

"Ready for lunch?" Lisa asked as soon as they were in ear shot of Spencer.

"Hey," Spencer said standing up and walking over to Lisa. For a moment he forgot where they were and he grabbed Lisa in a hug and kissed her hello.

The pulled apart as Penelope and Derek made some rather lewd comments and Spencer's face was bright red. Spencer cleared his throat, "So how was your flight?" he asked as he got his bag and after giving a shy wave to everyone left with Lisa for their lunch date.

"It was alright." Lisa said, "But I'm glad to be back." She put an arm around Spencer and leaned her head on his shoulder.

"Told you there was nothing to worry about." JJ said to Penelope who just rolled her eyes and asked who else was up for some lunch.
