A/N: Readers, here is the sequel I promised. The chapters alternate point of view… Well, anyways, I worked super hard on it, so read it and let me know what you think!

Relationships with a Vulcan Physicist

Chapter 1- The Science of Romantic Sheldon

"Observe him in his natural habitat… He can work quietly without any disturbance around those he is comfortable with. But when we bring in someone unfamiliar, he tends to freak out. Check it out. Howard, open the door." Raj whispered to Leonard. Raj was demonstrating his findings about Sheldon to Leonard.

When Howard opened the door, there stood the pizza delivery girl. Sheldon hopped out of his spot, dabbed his hands with hand sanitizer, and Lysol-ed the doorway before thrusting $10 to the poor girl, grabbing the pizza, and slamming the door.

"Score!" Howard yelped. "Raj, you were right!"

"I do not appreciate your betting on my personal habits. If Belle and Penny knew you were conducting this sort of mockery, they would, quote, 'have your necks.'" Sheldon sputtered.

They can't deny that. Hah. Once again, the infamous Dr. Cooper has trapped his comrades in a catch 22. Any comment they make after mine can most likely be used against them.

"Sheldon, calm down. We're just playing around." Howard slyly added.

Just before Sheldon could say anything else, Belle and Penny burst through the door.

"We heard ya'll got pizza. Can we have some?" Belle asked.

"Sure. We welcome your presence. Howard, I suggest you move, as you are sitting in Belle's spot." Howard shot to the other end of the couch to avoid Sheldon's wrath, while Belle plopped herself down next to her neurotic boyfriend. Sheldon continued to glare harshly at Wolowitz.

"Shel, calm down. I'm sure whatever he did is excusable." Belle comforted.

"Thank you, Belle." Sheldon took deep breaths and popped in the latest Star Trek movie while everyone settled down on the couch.

About half and hour into the movie, when Spock and Uhura start getting intimate, Howard paused the movie and spoke.

"I never realized it, but you two are just like them," Wolowitz pointed at Belle and Sheldon, and the TV screen. "Uhura is fluent in many languages, and Spock has no emotion. They are in love."

Raj whispered into Howard's ear, and Howard replied, "I know. I'm always right."

Sheldon was not amused. "I do appreciate your relating myself to Spock, but Uhura is constantly rude to Kirk, and Belle is nowhere near harmful."

"Sheldon, it's the thought that counts. Thanks, Howard, that's so sweet of you." Belle cooed.

Howard, satisfied, pressed play.

Sheldon woke up extra early on February 13th.

Knock, knock, knock.

"Leonard."

Knock, knock, knock.

"Leonard."

Knock, knock, knock.

"Leonard."

Leonard flung open the door. "WHAT?"

"I am aware that today is near to a specific date reserved especially for one's lover. I have never been in a quote, 'relationship', previously, so I would inquire you as to how to make said date, quote, 'romantic'."

"Sheldon, It's so early. I don't know. Get her some flowers or chocolate. Or an Argon Laser. I have no idea what she likes."

Leonard slammed the door in Sheldon's face.

* * *

Knock, knock, knock.

"Howard."

Knock, knock, knock.

"Howard."

Knock, knock, knock.

"Howard."

Howard cracked open the door to his room. "Why did my mom let you in?"

"Oh, she didn't. I had to climb in through the back window." Sheldon replied, easily.

"What do you need?" Howard clearly wanted to get rid of Sheldon.

"Tomorrow is an important day for persons in relationships, and I was sure you would know what to do, as you have seduced many women in the past."

"Just get Belle a gift card to Olive Garden. All my previous 'girlfriends' love that sort of stuff."

"But Belle isn't Jewish! Why would she like Olive Garden?"

Sheldon, once again, had the door slammed in his face.

* * *

Knock, knock, knock.

"Raj."

Knock, knock, knock.

"Raj."

Knock, knock, knock.

"Raj."

"What, Sheldon?" Raj yelped as he opened the door.

"Since tomorrow is Valentine's Day, I was wanting to ask you what I should do for Belle."

"Why did you come to me? You know I can't talk to women. I've never been in a relationship."

Raj shut the door, and stormed off back to bed.

* * *

Knock, knock, knock.

"Penny."

Knock, knock, knock.

"Penny."

Knock, knock, knock.

"Penny."

"Yes, Moonpie?" Sheldon was so frustrated, he didn't even retort to Penny's abusive use of his MeeMaw's nickname for him.

"Help. I have no idea what to do for Belle for Valentine's Day." Penny opened the door even wider, and sat Sheldon down on her couch as she explained him exactly what Belle likes and dislikes.

I will make this Belle's best Valentine's Day ever. Sheldon thought happily.
