After their first lunch period, Damien extended the invitation of sitting with him for future lunches, but told the blond he didn't care which he chose, but the seat would be available.
They parted ways once the bell rang and Damien returned to his altogether boring classes, eventually, sliding a slim laptop from his bag and "taking notes" during classes. What he was actually doing though, was preparing the report for his father and various underlings on why humanity wasn't ready for Armageddon.

Weeks slipped by, every day, Damien used his laptop in class under the guise of notetaking, on occasion, Butters would join him in the lunch room. Neither spoke overly much to their tablemate, but Damien noticed the days he was joined were days when Cartman was being particularly annoying.
It was one such day, that Butters trudged to Damien's table, his hair dripping and his jacket front soaked. Damien looked up from his own tray of food in mild curiosity.

Butters just glared at his own lunch and said nothing.

Casually, going back to his food, but before taking a bite of chicken, Damien asked, "You could make life very unpleasant for him, so why don't you?"

He felt Butters' gray eyes on him, but he didn't bother meeting the gaze, instead he focused on his overall unappealing chicken.

"What are you talking about?"

He did look up then, piercing red eyes met cold gray. "I think you are aware of what I was referring."

Butters stared at him for a few more seconds before breaking the eye contact and picking at his own lunch.

"What would be the point?"

The poor boy sounded almost defeated, defeated before he had even begun.

"Chaos."

Was all Damien said before the lunch bell rang.

He was aware of Butters watching him as he left the cafeteria, but he didn't look back.

Sitting in yet another tedious class, fine-tuning the report again, he jerked as his laptop opened a window he had not made. It was a chat window, black screen, silver text.

' Professor Chaos: Surprised?

P. C. : You shouldn't be. You know about my abilities. You know who I am.

P. C. : Just like I know who you really are, just try typing back to me. You'll see what I mean. '

Damien raised an eyebrow, Butters had somehow, hacked his laptop and was communicating with him. Under the name, Professor Chaos no less. Things on Earth just keep getting more interesting.

' Satan's Son : Heh. How did you figure it out?

P. C. : Unlike the rest of the cattle, I actually pay attention.

S. S. : That is very true. I should learn not to underestimate you.

P. C. : So you should Thorn. Since you know so much, which revenge scheme should I bring about on the fatass?

S. S. : Isn't that more a matter of how much chaos you want to cause?

P. C. : Sharper than you look.

S. S. : One to talk.

P. C. : I've got years worth of revenge to wreak.

P. C. : Talk later. Upgrade your security.'

And with that final line, the window was closed and Damien was looking at his report again. The bell rang seconds later, jolting Damien from his musings. He closed his laptop and slid it back into his bag before filing out of the class with the other students.

The rest of the school day, he was going over the conversation with Butters again.
He would upgrade his security. On his phone and laptop.
Upon school ending, he found a very shadowed spot to teleport back to his room. He placed his laptop, closed, on his bed, and stepped into the pentagram and began his meditation again. He looked through information in the "database" again, this time, he focused on upgrading security on laptops and phones.

Eventually, after he had learned all he could, he opened his eyes and drifted to the floor, his feet touching the carpet lightly. He opened his laptop and set about initiating a complete wipe of the entire thing, removing everything, next, after checking the time, he began doing the same to his phone as well.

He would have to teleport to school again, but this would be done before Butters was in range again, presuming, the blond did not know where he lived and could access his technology already. He dismissed the idea, he would probably be sleeping.

Damien stepped into his homeroom classroom right before the bell rang. He strolled to his seat and the teacher began attendance.
His phone and laptop were as tight as he could make them, though if Butters had already hacked him, even after wiping everything, he had used the wifi to download what he had needed. It was possible Butters had trojans across the city.

When neither Cartman nor Butters were at lunch, Damien felt something akin to worry, but he pushed it away firmly. The blond's whereabouts were not his concern.

Sitting in his last class of the day, laptop open and rebuilding the report, the familiar chat window opened.

' P. C. : Nice work. Took me all damn day to crack it this time. I can do better though. If, you trust me with your tech.

P. C. : Anyway, feel like meeting me for some coffee? You probably don't require caffeine, but the shop is run by a friend.

S. S. : I shouldn't be surprised..., Tweek Bros. I presume?

P. C. : Yeah. Tonight. They close at eleven. '

And with that message, the window closed itself and Damien was returned to his report. He typed a little bit more before saving the document and closing his laptop. He stared, vacantly, as the teacher prattled on about nothing.

Butters, or Professor Chaos, was proving to be much more interesting than he had first guessed. Interesting was definitely an improvement on the situation. Anticipation filled him, he pondered what Butters would want to meet in person for when they could obviously speak over the internet. Curious indeed.
