Normally, travelers like Leonard Ethan, when encountering insurmountable weather issues, would choose to find a place to set up camp and quietly wait for the adverse weather to pass.
This is of course a very normal and reasonable course of action, after all, the force of nature is often beyond what humans can contend with, and sometimes taking temporary refuge is not a bad thing.
However, the situation changed for Leonard and Joan, considering that the bad weather would not end in a short time, so Leonard simply took Joan and went home, just as if he had saved a game half-finished.
Without a doubt, this was a somewhat cheeky tactic, but it was very effective, at least resting in the warmth of their bed at home was far better than squatting in the icy wilderness.
