Helium

Simple and elegant, there's something almost perfect about a Helium atom.

The same can't be said for the rest of the world. Jemma and Trak are stuck on opposite sides of a planet dead set on destroying itself. And while they've kept their relationship safe from the chaos around them living inside a virtual world Trak created, even that can't stay forever. So perhaps it's worth giving up the life they have to try and find something as real and perfect as an atom of Helium.

Assuming they can survive.
