You and Clarke went hunting to the pond to catch fish. But you were caught by Anya and several grounders.  They dragged you to some basement in the middle of the forest, where you noticed a girl lying on a table.

"if your big sister doesn't save her, you're dead." She speaks short and coldly, lifting your chin with the cold tip of the dagger.

While your sister Clarke and Finn were doing everything to save the girl, Anya's eyes were on you, she was standing leaning against the wall. You looked back at her, it seemed to you that you would lose if you looked away.
