Monday Morning…Everyone knows how fun those are. Marty, as usual, got an accidental late start…mostly because he barely slept at all that weekend. The events of just that weekend were a lot for him. Going back and forwards in time…almost being stranded all together three times, and all while trying to save his best friend. Marty hoped that this week would bring him some peace, some rest, and no more temporal troubles.

As Marty entered the school, miraculously making it there just in the knick of time-despite his late start getting there-he bumped right into a girl.

She fell backwards, sending all of her books and papers that she was holding flying everywhere. She yelled.

Marty felt guilty for knocking her backwards, and helped her pick up her books and was about to send her on her way-except he hadn't seen her around before so of course, he asked:

"Are you new here? I haven't seen you around."

"New? Um, I've always been here?" she seemed offended that he would suggest she was a new student.

"Hm…" Marty was a bit confused, as he'd never seen her around… "What grade are you in?"

"I'm a senior!" she answered in a tone that showed that she didn't have time for him to be playing 20 questions with her, with the same tone of offense from before.

"Senior?" Marty however was also confused by that, since she was very short (which said something considering Marty wasn't really tall himself,) and very baby-faced. "How old are you?"

"15, dummy. Now I have to go so stop asking me questions!" she brushed him off like he was nothing and went her merry way to class…she entered the same 1st period that Marty himself had and he was even more confused.

Hill Valley's high school didn't have a very big student population in it, and the first period class was probably the smallest class he was in-yet he'd never seen this girl at all this year, or any year previously.

Marty didn't think much else of it, so he brushed it off for the rest of the day, but made a mental note to maybe talk to Doc about this…

~u~

After school Marty made a stop by Doc's lab. Coincidentally, the Time Train happened to show up right then.

"Hey, Doc! I have a few questions for you!" Marty yelled, as he approached his best friend.

"Yes Marty?" but strangely, Doc's tone seemed…off.

"We need to talk!"

"Oh-oh…well I'm a bit busy right now-" Now THIS was strange…Although Doc was a busy man, he wasn't usually too busy to talk with Marty.

"Can we talk later? This is important…" Marty added in.

"I-I'll try too…Well, you should probably head home now" Doc was being very uncharacteristically stand-offish…Never once, the whole time Marty had known him, had Doc EVER brushed him off like this…Marty cringed a little bit.

"O-okay…" Marty went home. Marty wasn't quite sure if he should ask Doc why he was acting this way, but he didn't know if he should pry into Doc's life.

Marty skateboarded home from Doc's lab.

~u~

The next day, after school Marty stopped by Doc's lab. Doc, unfortunately was not there. Marty entered however, with the key under the mat, and locked the door behind him. He kinda just stood around, not really doing anything in particular, waiting for Doc to hopefully show up.

Marty zoned a little bit, until he heard what sounded like something in the lock-Marty turned to the door, and the door swung open. Marty waited for whoever opened the door to enter-but what he wasn't expecting was for it to be the girl from the previous day.

"What the hell are you doing here?!" Marty was confused as all hell.

The girl screamed and punched Marty in the face.

Marty fell down, and rubbed his cheek where he'd taken the hit.

"What the hell are you doing here? Where the hell is Doctor Brown?" asked the girl.

"How did you get in here?"

"I picked the lock!"

"Why?"

"I have questions for Doctor Brown regarding-"

"Listen, he's not here right now…and why the hell did you think breaking into his lab would get him to answer questions-"

"The real question is what the hell is a slacker like you doing here!"

"Slacker? How do you know-"

"Oh please, Marty, you don't think I haven't heard of you before?"

"How do you know my name? I don't even know who the hell you are!"

The girl sighed, and pushed her purple glasses up the bridge of her nose. "Rinata Ishikawa-Potenza." She said "Or, Rin for short."

"Well, Rin, why the hell did you break into Doc's lab?"

"I already told you! I have physics questions for him!"

Then there was the popping of the Time Train-and Marty had to get Rin out of there quick.

"You need to leave!" Marty whisper shouted, forcing Rin out the window.

"I'm gonna be back you know!" Rin whisper-shouted back, before high-tailing it out of there.

Marty sighed in relief that Rin left before Doc entered. But he was going to find out what the deal with Rin was.
