Sometimes, Spencer wished that it was easy to get information from suspects. Okay, there were always the ones who liked to brag and had massive egos, but they were a minority.

"Come on, you can talk to us," Spencer tried to persuade the incredibly agitated man in front of them.

"I'm can't and you know why I can't!"

The man's voice got louder with each word until he was bellowing at him. Which was completely unnecessary, but it seemed to make him feel better.

"You are not experiencing any form of mind control, Mr Elgin," Spencer tried to tell their suspect.

He was using mind control as an excuse to not answer their questions. Apparently, they could both read his mind and therefore already knew what he was about to say and he didn't want his mind to be controlled even more than it already was so he wasn't going to tell them anything to prevent that from happening. Spencer wasn't sure why he believed there were degrees of mind control or why he thought answering questions would increase it further. Probably because they were government agents, the government in any form made people like this more alarmed.

But just because he could understand it didn't mean that it didn't frustrate him. He was starting to believe that Elgin wasn't their Unsub, but he was pretty sure that he knew something. The man was too paranoid to not know something. Hence why he was currently in their interrogation room.

"I am! You all are!"

"We aren't."

"You wouldn't know. The mind control would make sure that you didn't so they could go on controlling you. Your mind."

Right. Great. Elgin was definitely on the worse end of the whole mind control conspiracies. He might even be beyond being able to trick, he was that suspicious. Emily was being of no help whatsoever and was simply sitting back and watching with a faintly amused look on her face when she should be helping! They were kind of on a deadline here, or else there would be another victim! The guy was starting to give her suspicious looks too, which really wasn't going to help. They really didn't need him to be even more paranoid.

"How do you know that you aren't under some sort of mind control?" Spencer tried a different tact.

That actually made Elgin stop for a moment and give that some thought.

"I have protection! But even then, you can't be sure. Nobody can be sure!"

And they were back to the wild gesticulating. Spencer edged back a little bit to stop himself from accidentally getting punched in the face.

"But you feel like you have some measure of protection?" Spencer tried to lead him, but he wasn't having it.

"Mind control, I tell you!"

Elgin even thumped his fist on the table for good measure, spilling the glass of water he had asked for and had then proceeded to refuse to drink because of the "chemicals that damage your vision nerve from behind your eye out.."

Yeah, none of them could make sense of that one either. He didn't seem like he was having hallucinations, nor did he have any history of mental illness (Garcia had checked four times), just someone who was overly sensitive to conspiracy theories. He had informed them that only a certain brand of tinfoil could protect his computers. And that was the tamest of the theories he subscribed to.

"Get that water away from me!"

"I'm mopping it up, I'm mopping it up," Spencer reassured him. "See? All gone," he held up the sopping wet paper towels.

He recoiled so violently that Spencer and Emily lunged forward to stop him from cracking his skull off the floor. While they did this, the paper towels dropped to the floor, out of sight, making him calm down, thankfully. Though, he was still muttering about dangerous chemicals.

"Oh, for heaven's sake," Emily muttered as she stood up.

It looked like she had finally hit her limit. Spencer couldn't help but give her a nervous look, even though her ire wasn't directed at him. Look, Emily could be scary. Thankfully, she looked more fed up than angry.

"What if I said that yes, your mind was being controlled by someone else?"

Spencer looked at her with wide eyes. What was she doing? Why was she playing into his delusion? This was not a situation where playing into his delusion would be appropriate.

"I already knew that. That's what I'm trying to tell you!"

"Then you aren't going to be considered responsible for your actions," she said soothingly.

Which actually seemed to work. This was the least agitated they had seen him this whole time. Huh.

"But I shouldn't tell you," he mumbled, eyeing them both warily but less suspiciously than before.

"You can tell us," Spencer jumped in, feeling he was more suspicious of him now than Emily.

"No. I can't. I mustn't."

"That's the mind control telling you not to," Emily tried to coax him.

"It is, isn't it?" He said, his face clearing.

"Yes."

Two hours later, a very exhausted Emily and Spencer ushered Elgin out of the interrogation room. They had got nowhere with him. Absolutely nowhere.

They would have cut him sooner, but he seemed to have this ability to sound like he was about to give them useful information, but then he would stop and tell them about the whole mind control conspiracy. Spencer had never wanted to actually get rid of information from his brain, but this was making him reconsider.

"Thank you, Mr Elgin," Emily said through gritted teeth as he happily took a swig of water from the water bottle they had given him.

Apparently, that water was more acceptable than that in the glass they had given him earlier. Even though he had seen them pour it from a bottle. Whatever. If he had something in his mouth that meant he wasn't talking.

"I am removing all tinfoil from my house," Emily grumbled.
