As the others talked about how to detect MacPherson once he was inside the Warehouse, a thought crossed Caitlin's mind. Shaking her head, she looked at the others. "We may be getting ahead of ourselves," she said. "In order to get into the Warehouse is through the optical scan on the front door." She looked at Claudia. "All optical upgrades are done inside the Warehouse, on its computers, right?"
"That's right. That's why Artie won't let anyone access Warehouse files from their own computer," Claudia said before furrowing her brow. "But how strong is the panel? I mean, Myka totally kung-fu'd the dark vault panel and broke it. Who's to say MacOldPerson won't do the same with the optical panel?"
"Good point," Jack said as he rubbed the back of his head. "So we sure put the lasers up anyway."
"And water," Pete said. "If invisibility is caused by a refraction in the light, water droplets would break that refraction and give us an outline of MacPherson." When everyone looked at him, he shrugged. "I used to watch a lot of Bill Nye."
Shaking her head, Caitlin took a deep breath. "So we'll need to set up some lasers and a sprinkler system in the office of the Warehouse," she said before she glanced at the clock. "It's getting a little late. We should probably do all this in the morning."
"Sounds like a plan," Jack said as he stood from his chair and helped Fred stand. "Remember - use the buddy system and take your weapons with you if you have to leave."
