Chapter 4:

The silence in the apartment was deafening. It had been a week now since the feud and their unwillingness to be the first to blink had become apparent, through their long periods of silence and few brief moments of communication.

Leonard was watching Babylon 5 on TV; Sheldon was reading through Internet articles on his computer. The frostiness between the physicists had been felt throughout the gang too. Although nobody dared picked sides, it would soon become clear that sides would be taken for the future clash. Penny and Amy supported their own boyfriend's fiercely, whilst still maintaining their own relationship…just. Raj and Howard seemed content to watch the series of events unravel before them, whilst Bernadette tried to diffuse the tense atmosphere, wary of potential forthcoming events.

Restlessly, Leonard switched off the television. He though that it would always be more fun if Sheldon just gave him some well – earned peace and quiet, but now he was simply too bored. He glanced discreetly at Sheldon, who typed away speedily at his computer. Anything would be better than this now. The silence was killing him.

"No, I can't surrender and lose to him," Leonard mused as he walked over to the fridge to grab a snack.

Sheldon was engrossed in it: an interesting article about the history of the flag of Mozambique, when he sensed an opportunity. The lack of chitchat in the apartment had been just what he needed. His mind was now at peak potential, clear, and hungry for learning and his current work at Caltech was fascinating. Each new day, he practically bounded into his office and he returned home smugly with results that supported his theory, each giving him more confidence that he would outclass Leonard when it came to the prize that he had dreamed of winning since he was eight. He hadn't sensed yet though that Leonard was feeling the opposite and instead believed that this break was unfortunately aiding his nemesis too. However, Sheldon had prepared a string of tactics to ensure what would soon be his prize.

"Oh Leonard," Sheldon said innocently.

Leonard raised an eyebrow in surprise. "Yeah?"

"Would you pass me that bowl of yoghurt please?" he asked, masking a smirk.

"Oh, s-sure," Leonard obliged handing Sheldon the bowl.

"Thank you," Sheldon smiled, walking away from his desk. I think that I will eat this moist, nutritious yoghurt in my room."

Leonard stared, perplexed at his friend's crazier-than-normal actions. After a week of ignoring him, Sheldon asked for food as if the ice between them had melted ages ago. Pushing his thought to the back of his mind, Leonard grabbed a slice of pizza and sat in the orange couch (in Sheldon's spot) reading a Batman comic.

Sheldon walked past his bedroom with the yoghurt and quietly opened Leonard's room. He was unsure of how suspicious he had appeared but his ego diffused those thoughts as he quietly shut the door. Sheldon Cooper, PhD. Master of Stealth, Ninja of Cunning. He pulled back Leonard's duvet, grabbed the spoon of yoghurt and began to smear the pillows, bed sheets and duvet with wet, cold yoghurt before putting the damp spoon in one of Leonard's formal jackets…
