on earth, almost everyone died due to the cold snap, you stayed to live, but only as time went on it became colder and colder, but you heard from the prize-dweller in which place it was warm, you didn’t really believe it, but even here there was no point in living, you go to place where people start go, you decide go with Ethan and James

you walk already 12 hours in cold, James died from cold in turned out that he have some disease with legs so can't walk fast already after 2 hours and you let him stay here but it's understandable that there no chance of living, you with Ethan already tired walk
