Making My Own Happy Ending- HfjONE

I know the title sounds really awesome and cool but that's literally just what I'm doing

Liam Plecak has been stuck in this..place, for a week. If he's not trying not to cry over the computer being incomprehensible, he's sitting in the cabin staring at the laptop.
One day he decides to sit outside and try to make some plans, one that might, at least, get everyone on The Plain home. He had no idea how he was going to get himself back. Avoiding the top of Airy's head, his eyes glance over at the cave with the computer inside.

An idea?
