Mabel Pines stared at the letter in her hand, shocked. She hadn't heard from anyone in her family for a long time, but she had always hoped for someone to make contact. However, as time passed, no one, not even her twin brother, made the attempt. She often wondered why Dipper never made the effort to reach out to her. He had usually been so dependent on being in close contact with others, so his distance confused Mabel. "Maybe we just drifted apart" she thought to herself, "we can't stay young forever."
It was true, Dipper had moved on without giving his sister much thought. After high school, he continued to college and graduated with his Master's degree in Computer Science. He always figured it was impossible to lose touch with his twin, but he soon proved it to be very possible. The last time he had seen Mabel was when he was saying goodbye to her and their parents, going off to study at The California Institute of Technology.
Since then, Mabel had gone to the local community college and gotten her Associates degree in Fine Arts. She and Dipper slowly lost contact as their lives took separate paths. She did miss him, but knew nothing more about him than what she did when they had parted ways. She could only remember him as a young adult, waving goodbye with a bright smile on his face. It had been 5 years since then, which left Mabel without a clue of who he was with, how he looked, or what he was doing with his life.
But now, the crumpled paper and envelope in her hand intrigued her. The return address that was scribbled on was from Gravity Falls, Oregon. It looked as if it was written quickly, in a sloppy, blotchy pen. Mabel opened the letter to find a small postcard with a picture of the woods of her childhood summers in Gravity Falls. Memories flooded back to Mabel as she remembered the lazy days under the sun with the people she cared for so much.
"What is everyone up to anyways?" she thought. She flipped the postcard over to find the same writing as was on the address. It read, "Please come! Quickly!" -Stanford Pines.
There was another small piece of scrap paper inside the envelope, with a longer note. Mabel, noticing the urgency of the previous writings, swiftly snatched the paper and read with avid interest.
"Mabel, I have sent out similar cards to Dipper and other friends. We have a problem. Despite my current health issues, it appears that Stan has taken a turn for the worse. He has asked that you, along with others come see him. He was rather frantic, so I suggest you hurry. Please be here soon. I'm afraid we don't have much time."
As the urgency of the situation set in, the good memories began to fade. The bad memories emerged, with thoughts of Bill Cipher, Gideon Gleeful, heartbreak, and arguments. Although Mabel viewed Gravity Falls as a magical and youthful place, it had taken its toll on her and had made her realize that the world isn't always perfect.
However, she had never lost her charm and her wit. She still had the same bouncy hair and bright clothing choices as ever, but she felt incomplete without the people she loved. Her creativity was a lot for another person to handle, leaving her quite lonely at the worst of times. Most times, she wasn't sure if it was her personality, or aesthetic that drove people away.
She was sure of one thing, though. She needed to start preparing for a little road trip to Gravity Falls, and she needed to hurry.
