Dr. Sheldon Cooper had made an amazing discovery and had invited his friends around to his apartment to share in the excitement. He'd found a Blu-ray version of the classic movie Tron and had graciously invited everyone to share in his discovery; it seemed strange to him that they would initially be hesitant to accept this thrilling invitation; but everyone soon agreed to come over when they heard that he would foot the bill for the evening meal. At the moment there was only Sheldon, Leonard and Penny in the apartment and the two doctors were in the middle of a debate over what food they should order in.

"But it's not Monday, Leonard! We always order Thai food on a Monday, we have pizza on Thursdays which really only leaves us Italian tonight."

"Sheldon, pizza is Italian," Leonard tried to explain and was overruled again.

"Not the way I order it, it's not; and besides which, I'm paying so that means I get to choose. Ha, ha." Sheldon quipped and telephoned the order in. Howard and Bernadette arrived a few minutes later and cozied up next to each other in the large armchair beside the TV. Sheldon was in his usual spot with Leonard at the other end with Penny sandwiched between them. Raj couldn't make it that evening as Cinnamon had been taken to the vets for her yearly vaccinations and he'd decided that he couldn't leave his precious baby on her own in the apartment when she was clearly traumatised by the day's events.

"Dinner should be here soon, shall we watch the previews while we're waiting for it to arrive?" Leonard asked, fingers poised over the remote control. Sheldon looked up and arched an eyebrow in derision.

"Leonard, has it completely escaped your attention that we are still waiting for Amy's arrival? Honestly, what would she think if we were to start watching without her presence?"

"Probably something along the lines of 'thank god, it's nearly over'," Penny murmured to whisper in Leonard's ear, completely forgetting Sheldon's acute sense of hearing. The snort coming from his end of the couch soon let her know that he'd picked up on her snide comment.

"What time's she coming over, Sheldon?" Howard called out, looking at his watch and calculating how long it would be before he and his little snuggle bunny could escape from Sheldon's clutches and go back to their apartment.

"Hmm…?" Sheldon said distractedly as he looked up from his watch, and then picked up his phone to check whether he'd received any missed calls or text messages explaining her delay. Howard chuckled softly, it was the first time he'd ever not had Sheldon reply to any of his questions; even if they were in a sarcastic vein.

"Howie asked what time…"

"I heard him, I just can't understand why she wouldn't have called to explain her absence; it really is most unlike Amy to be late. You know how punctual she is, we are rather alike in that manner you know."

"Yeah, we know." Leonard remarked sarcastically from the other end of the couch and yelped when Penny punched him lightly on the arm. "Hey, that hurt!"

"It was supposed to, you big dummy! Can't you see that Sheldon's upset?" Penny sighed impatiently, honestly it was tiring sometimes having a boyfriend with no filter from his brain to his mouth. She shifted a little closer to Sheldon on the couch and risked lightly patting his arm. "Why don't you give her a call, Sheldon?"

"And act like some hippy dippy who's tracking his girlfriend's every move, no siree!" Sheldon's fingers were itching to snatch up his phone and do exactly what Penny suggested but he didn't want everyone to think that he was the type of person that would be lead by his glands.

"Alright, sweetie. I'll give her a call instead, okay?"

"Thank you, Penny, thank you!" Sheldon beamed over at his neighbour who smiled back in return before pulling her pink phone from her back pocket and scrolled through until she found Amy's number.

"Ames…? Where are you? We're all waiting on you at Sheldon's?...Oh…well, okay…sure sweetie, I'll tell him…See you later..Bye…" Penny disconnected the call and turned to face the rest of the group. "Amy's having a little problem at the lab, she said to start without her and she'll be here as soon as she can."

"Little problem, what kind of little problem?" Sheldon leant over to stare at Penny, demanding more details.

"She didn't want to go into details over the phone, but it sounded like she was pretty upset…she said that she didn't feel like eating, but would come over for a bit once it's all cleared up…Maybe an hour, that's all she said." Penny patted Sheldon's arm again and he sank back into his spot. He leapt up as he heard the knock at the door, and raced over to pull it open – only to see that it was their take out delivery instead of Amy.

"Oh…thank you." Sheldon handed over the money and accepted the carrier bag of food, which he set down on the coffee table and watched as everyone started to pull out their orders.

"Sheldon…?" Leonard's voice cut through his distracted thoughts and Sheldon half turned to face his room mate and murmured distractedly.

"Hmmm….?"

"Your lasagne's getting cold." Leonard tapped the foil container containing Sheldon's order. "You know you don't like to let your food get below 160 degrees; it's unhygienic and you'll have to throw it away."

"No, thank you, Leonard. I think I'll wait until Amy gets here and warm it up then. She may be hungry by then and someone's eaten her spinach cannelloni." Sheldon's quiet remark came as a complete surprise to the room; first he was displaying anxiety over his girlfriend's late arrival and now he was offering not only to reheat his meal – but to share it with her as well! Who was this man, and what had he done to the real Sheldon Cooper?

"Maybe we should just start the movie and you can catch her up on the parts she missed later." Bernadette suggested as she snuggled next to Howard in the armchair; they fit perfectly side by side in the chair due to their diminutive statures but it was still nice and cosy.

"I bought it for Amy to watch, it was one of her favourite sci-fi movies…" Sheldon remarked, and then quickly pressed play on the remote before anyone could remark on his hippy dippy habit of buying things that he knew his girlfriend would like. "There will be no need to fill her in, as I am sure her memory skills are almost as excellent as my own," The group chose not to remark on his comments, knowing that it would only make Sheldon all the more uncomfortable.
