Author's note: The final chapter! Sorry for the long wait!

The next day, Marty wakes up from a sound of knocking coming from the door. She groggily opens her eyes and stood up as smoothly as she can so that she wouldn't wake Emmett in the process. Marty opens the door to see a man standing there.

"Are you miss Martin Seamus McFly?" The man asks.

"Uh, yes?" Marty asked bewildered.

"I'm from Western Union and I got a letter for you," the man said giving Marty a package. Marty took it as the man gotten out his clipboard. "Please sign," the man says as Marty nodded and signs it. The man puts it away and before he leaves, says: "That will be your last letter from him."

"Wait, what?" Marty asks blinking.

"There was a note attached to it with a generous amount of money on it. It's from your friend," the man said and he smiles politely to her before leaving without another word.

Marty closes the door and she turns around and sees Emmett, sitting upon the bed staring at her. "Whose it from?" He asked.

"I have no idea," she lies with a shrug as she put the package on the table.

"Marty…"

"Emmett, why don't you take a shower first? We have to freshen up before heading to the school to present our findings," Marty said.

Emmett frowns at her but nodded anyway, "Very well," he replies as he got out of bed and Marty blushes at the sight in seeing him naked. "Do you want to join me?" He asked smirking at seeing Marty's red face.

"At that rate, we won't be able to get anything done," she said.

"O-Okay, you'll be missing out some fun," Emmett teases as he went to the bathroom to freshen up.

Marty shook her head in amusement and she waited to hear the shower going on before turning to look at the package and opening it. There was one piece of paper inside and she took it out to read it.

Dear Marty,

The time vehicle is finally working again! I'm sorry it took this long, but I'm sure you have a good experience there? I sure have since the memories are catching up to me by now (Marty blushes again at the thought) and it is a very pleasant feeling.

Anyway, the judging should be somewhere in the evening so I'll swing by and pick you up at 8pm. Meet me where I dropped you off when you headed to Hill Valley. Do you still know where? You probably do, and if you don't, well…just ask my younger self.

Enclosed with this letter, I gave you some extra cash in case you need it before I come by. Take a look around before you leave, Marty. And don't do one last minute drastic changes!

Your friend in time,

E.L.B "Doc."

Marty squealed happily, she was finally going home! But first thing first, they need to go to the high school and show the evidence of Edna.

The day went by in a blur as Marty tries to be happy for Emmett where in fact she was nervous. They entered the school at precisely five o'clock and saw that there were people already there alone with the judges. Marty looks around and saw no sign of Edna.

They waited in line until it was there turn. "Name?" One of the judges asks gruffly.

"Emmett Lathrop Brown, I have evidence where my invention is being sabotaged," Emmett said as he took out the pictures to hand to the judges.

The judge in question looked at the name and at the photos before turning to look at the head judge. "He is the guy whom I spoke to before," the head judge said, "we need a few minutes discussing this. So please…" before he could finish, they were interrupted.

"NOW JUST WAIT A MINUTE!" A voice exclaims angrily as everyone turns and Marty saw Edna walking with a man beside her.

"Father…!" Emmett cries shocked.

That's his dad?! Marty thought surprise as neither looked like one another. Emmett must had gotten his looks by his mother, she thought.

There was an argument between father and son for a moment as the judges tries to calm them down before calling security. "ENOUGH!" Edna screeched as everyone halted on what they were doing or saying and turns to look at her. "This is insane! He shouldn't be here in the first place to participate!" Edna exclaims pointing at Emmett.

"And why shouldn't I be? I don't have the right to follow my dream?" Emmett asked angrily.

"Your dream is to follow your father and be a judge! Not some scientist!" Edna said.

Emmett seethed, "No Edna. That's your dream, not mine. You follow in my dad's footsteps, I'm certainly will not. No offense father, but building and inventing stuff has always taken an interest with me. Just how Elizabeth is into singing," he said.

"She is?" Emmett's father, Braun Brown asks slowly.

Emmett nodded, "Father, please. Just let me do this and I'm sure you won't regret it," he pleads.

Mr. Brown turns to Marty who froze. "And you, who are you to my son?" He asked.

"I'm…" Marty began and she fidgeted a bit as she looks at Emmett who was staring at his father. Marty turns to look at him, "I'm his girlfriend, sir," she said.

"WHAT! You're not!" Edna screeches.

Marty nodded, "I am too. I've been supportive with Emmett's idea ever since I came here. I know I have to leave him soon," she said sadly, "but I promise you, wherever I am, I will support him until I could return to him by his side," she said confidently.

Unknown to Marty, Emmett was smiling. Braun Brown sighed as he looks back at forth between his son and Marty, "God forbid I try to make you do what I'm doing right now, but I can't stop your dreams, can I?" He asked as Edna was staring at him, wide-eyed now.

"Father…?"

"Mr. Brown…?"

Braun Brown smiles as he looks at his son, "Go for it, son. I'll talk with Elizabeth when I get home," he said as Emmett's face lit up.

"You can't do that!" Edna screeched.

"SECURITY!" Braun bellows and several security guards came to take a screeching Edna away.

Everyone blinked in surprise before Emmett turns to look at the judges whom were stunned as they had been. "My name is Emmett Brown and I am here to officially turn in my invention on Saturday," he said confidently with a beaming smile.

When the whole entire fiasco was done, it was already 5:30PM when both of them had gotten out of the high school. "I can't believe father agree with me now! And it's all thanks to you, Marty!" Emmett said as he turns to look at her but saw a sadden look instead. "Marty…?"

"I only have less than two hours before I leave town, Emmett. I don't want to leave, but I must," Marty said softly that Emmett almost didn't hear her.

"Then let's have dinner together for your last time here," Emmett said as he grabs her hand and the two went off to a nearby restaurant.

It was now 8:05PM as Marty went to the spot where she supposed to be meeting Doc. She was late as saying good-bye to Emmett had been a hard thing for both of them. Before leaving, Marty had quickly changed back into her clothes. Marty was out of breath by the time she saw Doc leaning against the DeLorean as he waits for her.

"Doc…" She breaths out.

Doc was staring at her as if he was unable to move. He blinks once or twice before he began to walk towards her and Marty did the same before the two crushed into an emotional hug. "Marty…" Doc said as if he couldn't let her go.

"Oh Doc! I…." Marty began but she was loss for words.

"Shhh, everything is alright now, Marty. I'm still the same Emmett that you just left a while ago," Doc said softly to her.

"I know, doc. It just feels, I don't know…" Marty stammers.

Doc nods in understanding, "No matter what age I am, I still love you, Marty. I will love no other," he said.

Marty stares at him and the two leans in to kiss each other. It was Marty that broke off the kiss a minute later. "So, before this happened, did you loved me?" She asks with a grin.

"We should go back to our time," Doc quickly says as he was returning to the front seat.

"Doc! Tell me!" Marty whines.

"Another time, Marty," Doc replies.

"Aw, you're no fun," Marty says shaking her head as she too went to the passenger seat.

Doc shook his head in amusement as he was glad that he was finally going home with Marty.

End...

Sorry for the abrupt ending! My original chapter got deleted by Jotterpad (an app that I use on my phone to write my stories anywhere) when it updated it's contents and I couldn't get it back. I was almost done too! So I tried my best from memory and how it was before it got deleted. I hope you guys weren't too disappointed...
