Currently in the dropship on Earth, Clarke is checking Jasper's pulse after he was speared by Grounders.

She tells Monty to keep an eye on Jasper while she goes to get him some water.

Once outside the drop ship, she hears a 13-year-old-girl, Charlotte, crying out in her sleep and goes to wake her up from her nightmares.

Charlotte tells Clarke that she sees her floated parents. Clarke tells her that her dad was floated, too, and she asks Charlotte what got her locked up.

Charlotte tells her that she assaulted an Ark Guard who took her parents' things to the redistribution center.

Clarke points out a bright star in the night sky and tells Charlotte that the Ark up there is something they can move past and the ground is their second chance.

Meanwhile, two random people named Trina and Pascal are wandering around in the woods, having been lost for two days.

Pascal promises Trina they'll find the drop ship tomorrow when a rumbling sound is heard and a yellow fog starts to envelop them. They start to scream that it burns.

The next day, Bellamy is teaching John how to throw sharp objects when Atom arrives and tells him that they haven't been able to find any sign of Trina or Pascal.

In the background, Jasper's cries of pain echo throughout The Camp and Atom tells Bellamy that it's not helping morale. Bellamy tells John to stay behind while he takes a group hunting.

You and your friends are back at the camp, doing whatever, when people hear screams out in the distance and a yellow-ish fog comes closer. You and few people realise it's acidic and would kill a human, you must act...
