Flashback:

It took a while but he finally got what he wanted. Scopolamine was a notoriously hard to get hold of drug but now he had it he could do whatever he pleased with the younger genius.

Walter was just where he wanted him deep within the rabbit hole and gloriously unaware of anything around him. Collins could easily inject him while he was in this state with Walter completely unaware (and he had done many times in order to get the bloods needed for Marks multiple experiments) but while Walter was oblivious to his surroundings he was only able to focus on his work-he couldn't follow Mark's instructions the way he needed him to.

It was called 'Devils Breath' for a reason.

A little of the drug was good for nausea but a fair amount of it could leave a person with no free will until the drug wore off- with the added bonus that the victim would experience amnesia. Using it alongside Xanax in the right balance (as Mark was about to do) the effects would be magnetised.

With Walter so far down the rabbit hole Happy wouldn't notice anything else amiss when she returned- not that she could stop him anyway. "There we go just enough of them to make you compliant for as long as I need you to be, not enough to kill you." Mark whispered as he stuck the needle into Walter's wrist.

The effect was quicker then Mark anticipated. Walter's arm fell from where he had been working ready to follow any instruction given. Mark grinned as he thought of all the things that would now be possible now. "Remove your clothes" Mark told him authoritively. Instantly Walter began stripping down as if he were eager for what would come next.

"Good boy" Mark cooed appreciatively. "Now take this" he started grabbing a pot from nearby he had saved for the occasion and forcing it into one of Walter's hands "and wank into it. But keep your head up! I want to see your face as you cum for me".

Walter was quick to follow his instruction- something he'd have never done if he were lucid. Mark knew he had a thing instead for one of the local Cheerleaders. A girl he planned to ruin as much as she had ruined Walter- though they'd never spoken. He knew Walter had been watching her- admiring from a far. Not quite stalking but never failing to miss her shows and distracted by her presence whenever she was near.

Mark knew enough to recognise he was jealous, But no matter. The filthy whore wouldn't stick around long when he was done with her with the added bonus that she would unknowingly take a piece of Walter away with her. He'd bring her back when the time was right of course- after all what she would unwittingly do for him was a integral part of his plan. As Walter moaned as he came apart Mark wondered if it was the whore that he thought of- if he was capable of any thought at all.

Minutes later Mark had gotten everything he needed from Walter that day for his plan to begin to come together but one thing remained that he needed to happen. His cock twitched in anticipation, it'd been hard from the moment Walter had stripped down "On your knees" he instructed groaning in relief as he freed his cock from his trousers. Holding it in front of the other man he grinned knowing he couldn't be refused "now suck it like you love it" he demanded moaning loudly as Walter complied.

It didn't take as long as he'd have liked before he'd came, his hands grasping Walter's hair in a way that would've been painful if Walter was capable of acknowledging pain at that moment. "Maybe next time I'll take that tight little arse for a ride" he said groping Walter's behind tightly.

He smirked to himself as he commanded Walter to dress himself again and sent him back to the blackboard to continue his work. By the time he came round Happy would have cleaned him up, brushed his teeth and fed him and no one would be any the wiser what'd happened. Speak of the devil-

"Collins! I told you to stay away from him you're making him sick!" Collins smirked to himself, she had no idea how much.

Dragging Walter away from the blackboard Happy forced Walter towards the bathroom determind to get him clean before she once again forced a tube down his nose in order to get him to eat. Happy had long ago stopped giving Walter instructions while he was down the rabbit hole knowing he wouldn't respond anyway so she'd have no idea he would've followed her commands.

"What a caring wife" Mark commented sarcastically.
