Phil's head rested on the main computer console as he slept. Sometime during the night, Gabi had crept in and draped a blanket over the sleeping telepath. She tiptoed back in carrying a mug of coffee, which she placed on a table next to the console.

Phil stirred slightly. His eyes opened slowly. "Man... I was down here a lot later than I thought." He turned and noticed the coffee, then the blanket, then Gabi. "I don't know how I got along without you," he told her.

Gabi smiled. "Good morning, sunshine. You were down here all night."

Phil nodded. "I wanted to get everything just right."

"Which explains why you hacked into the FBI mail servers," Gabi said, motioning to the screen.

Phil sighed. "Sorry. Just wanted to stay a step ahead of things."

"You're really worried, aren't you?" Gabi asked.

"A little," Phil admitted. "But I'm more concerned about what would happen to the team if things went south while they were out in the field." He looked around. "Are you familiar with the concept of a panic room?"

"Didn't like the movie," Gabi answered.

Phil chuckled. "It's like this. In an emergency, when you know security has been compromised or something very bad is about to happen to the area where you're located, you need to have one place you can go where you can be sure nothing will get to you. So you create a chamber that's about as close to invincible as architecture and materials will allow.

"This room," Phil said as he gestured around him, "is my definitive idea of that concept. The walls are made of steel-reinforced concrete two feet thick, with a thin layer of lead to dissipate radiation. The room is airtight, watertight, and impervious to pretty much anything short of a "bunker-buster" bomb specially designed to destroy hardened military command centers - but even that would have to come through the rest of the building. Basically, the whole building could come down around us, and this room would go untouched."

"But what about the people inside?" Gabi asked.

"There's a vast amount of supporting infrastructure connected to this room," Phil explained. "Once the outside of the building is completed, we'll be mounting solar panels to collect energy to run the systems here, and also to supply banks of solar batteries down here in case the power fails. There are filters that purify air and water taken in from the outside and store it in tanks. Those air and water supplies can last almost a week, and in the event that they run out, the filtration systems can remove almost all known pollutants and poisons from the outside air and water. There will be stockpiles of food, medical supplies, and weapons. And the list goes on."

"Sounds great," Gabi said, "but how do you plan on protecting all those things?"

"Comprehensive access control," Phil replied. "I'm finishing up installing the hardware for fingerprint, voiceprint, and retinal scanners now. But the most important element of security is that the door opens from the outside only once, to let one person in. After that, that person is responsible for letting others in - or keeping them out."

"Sounds like you've been working on this for a while," Gabi said.

"Me and Grissom put the system together, and Charley and Priest added a few ideas of their own." Phil sipped his coffee. "We've got all sorts of plans put together."

"And you didn't consult with Leslie?" Gabi asked.

Phil looked at her. "No. Does that surprise you?"

"I figured you would have found a way to include her," Gabi said.

Phil frowned. "No. We're currently not speaking to each other."

Gabi laughed. "Is this high school again?"

"She told me she likes me," Phil said.

Gabi couldn't contain another laugh. "So?"

"So, I'm not interested."

"Not at all?" Gabi smiled at him.

"Gabi! I'm with you!" Phil was beside himself. "What does it matter whether or not anyone else interests me?"

"That's not what I asked," Gabi said.

Phil sighed. "Okay While you were gone, a lot of stuff happened. Leslie and I were kind of... close. But that doesn't matter now, does it?"

"Phil," Gabi replied, "you don't have to hide how you feel about another woman to avoid offending me. I'm a big girl, and I can handle knowing that I'm not the only one in your life. You're your own person, and you've got to make your own choices."

"Gabi," Phil insisted, "I love you. You know that."

Gabi looked at him. "I know. But I'm not going to be around forever."

"What do you mean?" Phil asked.

"Don't worry about it right now," Gabi instructed him. "You've got a lot of work to do." She crossed the room and looked at the heavy steel door. "So tell me how this retinal scanner works."
