A/N: Again, no Beta all faults are mine. This is a bit of a longer one, and I'm still working on how to have everyone there that I want and juggle all of their dialogue.

Penny was trudging up the stairs after a double shift at the Cheesecake Factory, wondering if she had any wine left when she heard shouting. With a quick eye roll she hurried up the last flight, hoping she could get them to at least fight quietly. She had a rough day and wasn't about to let them ruin Penny Time. The closer she got to the fourth floor, the clearer the argument got. A hyper Lenard, an excited Howard, and a very southern Sheldon. No Raj? Penny cocked her head to the side. Ahhhh, a girl was shouting back.

"I know the Tarids isn't real! Do you think I'm stupid? Trust me, I'm not stupid! I have an IQ of 178, which I disputed but my father told me no. Repeatedly. And I'm not crazy either, he had me tested for that as well. It's a mock up called the Tardis! Are you sure you're not the one who is stupid?" A very female voice shrieked. Penny decided not to knock (again) and just barged in (again).

The scene was an odd one. Sheldon was standing, completely confrontational. He standing completely straight, arms crossed across his chest. There were veins threatening to pop out of his neck at any given moment. Directly across from him, standing in front of the island was what looked like an attractive girl, who apparently knew what a Tardis was. And she was standing up to Sheldon. Penny liked this girl already. Lenard was sitting in his chair, a look of complete fascination on his face. He was staring like he used to look at Penny. Utter and complete devotion. Creepy utter and complete devotion. Raj wasn't saying anything of course. The second estrogen enters the room he turns wonderfully mute. Howard was the one the scared her the most. He wasn't leering like he usually does with an attractive lady, and he wasn't making obvious double entendre. It looked like he was in complete science mode. No emotions, all logic. Penny had only seen that look on him a handful of times, mostly when he was in the running for the whole astronaut thing.

"Stupid?! Stupid?! Listen here Missy, I've been called a lot of things in my life, but I will allow no one to call me stupid! You may or may not have an IQ of 178, but mine is 187. I also have two doctorates and was the youngest person to win the Stephenson award. Who are you to call me stupid?"

"Sheldon, you need to calm down."

"Calm down? Calm down?! Lenard, do you not see that this girl is trying to 'pull one over' on us? There is no way that she is from the future. We have no proof. She could very well be trying to trick us and kill us in the night so that she could take all of our comic books, though why a girl that attractive would be interested in comic books is beyond even my remarkable intelligence." Penny didn't know why, but she thought that she should be insulted by that statement.

"Proof? Proof of what? What are all of you yelling about?" Penny asked.

"Penny? Hi! Yes, well this is Marie and ..." Lenard was interrupted by Sheldon.

"This child is trying to tell me that I have invented a time machine with Howard no less. if I ever did perfect a time machine, I'd just go into the past and give it to myself, thus eliminating the need for me to invent it in the first place. Therefore.."

"How could you give it to yourself if you haven't perfected it yet?" Marie cut in. "If it wasn't mastered you wouldn't give it to yourself yet for fear of self criticism. You are always your worst critic. Why don't you believe me?" The question was desperate.

"Well, first off right now time travel is impossible. And if I ever did make a time travel device, I would sure as shooting be the first test subject. Twenty years would not be enough time for technology to advance. We would not have the ability to travel through time yet. Also, your clothing is tattered and worn, obviously you are homeless and in need of shelter."

"I'm sorry. I just was ripped through the time vortex and placed here due to your incompetence, so please pardon my clothes." Was the sarcastic reply.

"What a minute. Are you saying that you are from the future?" Penny interjected. Two pair of eyes focused on her immediately. "Well, are you?"

"Yes, I am." Marie paused for a minute. "And you are?"

"Penny."

"Marie." She said with a soft smile on her face.

"Excuse me." Howard said. "As much as I hate to admit this, Sheldon has a point. This is an unbelievable story, and as bad as I want to be a part of creating a time machine, I think we do need some sort of proof. Can we see this Tarids?" Marie slightly un-nerved him with her stare.

"Yes, you may." She immediately set about undoing the contraption that covered her upper chest and arms. Once it was off, she laid it carefully on the coffee table for inspection then wandered over to one of the many whiteboards in the apartment and erased everything on it, ignoring Sheldon's squawks and began writing out an equation that Penny couldn't even begin to understand.

"What is that?" Penny asked her.

"Sheldon's equation for time travel." Marie told her. Sheldon immediately went to the board, determined to prove this insolent child wrong.
