They leave the next morning. Einar carries Dean, and Kymil takes all the bags. The bags end up freezing by the end of the day, but they manage to get the tent up and food cooked.
They sleep, and Kymil keeps watch
Dean and Einar grow ill, Dean more than Einar, and their travel slows. Kymil, despite Einars worries, dawns Einar’s spare clothes designed to warm and carries Dean in his place.
Kymil grows weak from the warmth, but pushes through for his friends’ sake. Hoping his freezing body was properly insulated by the clothes and not making Dean more sick than she was.
Thankfully, they find the bunker before nightfall.
