Back In Time (GF Timestuck AU)

Mabel Pines finds herself in a little bit of a pickle:

She and her twin brother Dipper find the time-traveling tape and use it to go back in time--

The only problem?

During the time-jump, they get separated.

Now, Mabel is left alone, with no knowledge of what happened to Dipper.
The odds weren't completely against her, though--fate brought her a very familiar person to be her guide.
