Frozen final

There are three teams left in the wilderness. Pain and lack of sleep are pushing one team member to the limit, while his partner is busy with an art project and taking off his clothes. For another team, the doctor warns against the cold nights and hypothermia and orders the shelter to be insulated with moss. When is it time to go home from the wilderness? And who will be picked up by the family as the winner of Alone in the Wilderness?
