We keep our heads, Rory. We look around, investigate, figure out what's going on. There must be clues about this forcefield somewhere, we just have to dig deeper.

And then, maybe, just maybe, we get everyone off this island and back to their own lives.

That is, of course, assuming that neither of us vanish or get killed by monsters or change into a different version of ourselves and don't turn back or get shot by one of the other residents.

Again.

I may have forgotten to mention - reality is a bit more... wibbly, here. Much more than it aught to be.
