The first three chapters takes place before the end of season 6. This chapter takes place after the start of season 7. Just in time for the start of season 7 booya. Who is ready for it?

Over the next few weeks Billy and Kat got to know Sheldon, Leonard, Raj (or the drunk Raj), and Howard better. Whenever Raj had something to say to Kat, he would whisper it to Howard. Billy and Kat did meet Amy and Bernadette. One night Billy and Kat had Sheldon, Amy, Howard, Bernadette, Leonard, Penny, and Raj over.

After everybody left Kat said, "Those guys make Bulk and Skull seem normal."

"Bulk and Skull were worse before you moved to Angel Grove."

"Let's hope that Sheldon does not knock on our door and say William and Kate," Kat said.

"I agree, he might get tongue tied. I wonder if anyone has diagnosed him with OCD?" Billy asked.

"I doubt he would say Prince William," Kat said.

"He seems more sociable around me. Although the other day he did bug me. He asked how we met. I told him the same story I tell everyone that has never been a ranger. I said that we met in high school, but we did not start dating until years later. An unfortunate event brought us back together. Then he got nosy and asked what the event was. I said it was none of his business. Then he said that he wanted to know. Without telling him the whole truth, I said an old friend of ours who was like a family member died. When I found out about it, I left my space exploration and return to Angel Grove. I also told him my my exploration was top secret. Then Leonard stepped in and told him to stop integrating me," Billy said.

"Oh my," Kat said.

Later that night, Sheldon was in deep thought.

"Something does not seem right about Billy," he said.

"You are now calling him Billy?" Leonard asked.

"All of you do, so I might as well," Sheldon said.

"What doesn't seem right?" Leonard asked.

"His story on how he met his wife. I get it that they did not date in high school, but you don't just leave a space exploration for a funereal," Sheldon said.

"Oh will you knock it off and leave the guy alone. He probably left a day early or something like that!" Leonard said.

"I will not," Sheldon said.

Without Sheldon seeing him, Leonard reach for his cellphone and pressed a few buttons.

"What are you doing?" Sheldon asked.

"None of your business," Leonard said.

After Leonard pressed a series of buttons he put the phone to his ear and said, "Hello Mrs. Copper."

"Oh no you didn't," Sheldon said as he started chasing Leonard around the apartment.

A minute later, Sheldon took the phone away from Leonard.

When he looked at the screen he said, "Hey wait a minute, you tricked me. You didn't call my mom, you were just going through your text messages."

"Just because I didn't this time doesn't mean I won't," Leonard said.

"No? You wouldn't," Sheldon said.

"I could and I might if you don't leave Billy and his story alone," Leonard said.

"Leonard," Sheldon said.

"Yes?" Leonard asked.

"Will you drive me to Angel Grove?" Sheldon asked.

"Hum let me think about it. NO! DROP IT ALREADY! GOOD NIGHT!"

Somebody is cranky. Sheldon thought.

Sometimes I wonder if Sheldon was ever a real boy the way he acts. Leonard thought before he went to bed.

The next day, Sheldon was asking Howard and Raj to drive Him to Angel Grove.

At lunch Howard said to Leonard, "Do you know why Sheldon wants Raj or I to drive him to Angel Grove?"

"He believes Billy is hiding something," Leonard said.

"We all have something that we hide," Raj said.

"What do you have to hide? Everybody knows you are not from here and you can't talk to women without being drunk," Howard said.

"It's not my fault," Raj said.

"You know, every since I got back, Sheldon has seem weirder than before," Leonard said.

"I think that's just you," Howard said.

"What we should really want to find out is how Billy got his wife," Raj said.

Howard and Leonard face palm each other.

"Hello fellow Dr.'s, and Howard. I have a theory on that maybe it's not women you like but Howard," said Sheldon.

"Now you sound like my mother," said Leonard.

"Why do you think Billy is hiding something?" Raj asked.

"I don't think, I know," Sheldon said.

"Come on Sheldon, you don't know anything," Leonard said.

"In what world would a scientist leave his work for a funeral or a woman?

"This one!" The guys said in unison.

"That is what you do if a close family member dies. Come on don't tell me you wouldn't go back to Texas for your mom's own funeral," Leonard said.

"You know Sheldon, not everyone can buck social convention like you," Howard said.

"Leonard, would you fly back to New Jersey for your mom's funeral?" Sheldon asked.

"As awkward as the trip would be, yes. I think you would accompany me," Leonard said.

Howard and Raj started laughing.

"Anyways, maybe Billy is hiding something. Maybe he was a Power Ranger," Raj said.

"Don't be ridiculous," Leonard said.

Sheldon said," You know, I never thought about it."

"Please don't give him any ideas. Especially the ludicrous ones," Leonard said.

"You know, we have three of the brightest minds at this university, and Howard. I think I have an idea of how we can prove if Billy is what Raj thinks he was. Howard this is where I think your engineering skills might come into play. We build a time machine and go back to 1993, particularly Angel Grove," Sheldon said.

Leonard, Howard, and Raj groaned in unison while face palming.

"Hey fewwows, what has Coppew done this time?" Barry Krimpke asked after he walked up to them.

"Nothing yet," Leonard said.

"Hey Krimpke, you know Billy Cranston, right?" Sheldon asked.

"You mean the watest hiwe in the physics depawtment? Suwe what about him?" Barry asked.

"I believe he is hiding something. I have an idea to build a time machine and go back twenty years to his hometown of Angel Grove. There I plan to study the habits of young Billy to see what the modern day version of him is hiding," Sheldon said.

"You want these thwee to hewp you? Do you need my hewp?" Barry asked.

"Perhaps if we need plasma to make the time machine work," Sheldon said.

"You are nuts Coppew. Of aww of the wack jobs, you are the wowst," Barry said.

"Hey Krempke, say be very quite, I'm hunting for rabbits," Howard said.

"Hey now, I know why you want me to say that. Who do you think I am, Ewmew Fudd?" Barry asked before he walked away.

"Howard, you know how I feel about making fun of others, but I must admit, that was pretty funny," Sheldon said.

If you do not watch Big Bang theory the character Barry Krempke does have a speech problem.
