I love the stuck-in-a-snowstorm trope! Something about forcing people to face each other in a way that makes truth happen? IDK.

I am very intrigued by your other theme. Characters who are the collateral damage of someone else's good cause. I think there's a lot of gold to mine here, and I can imagine there are perhaps some writers/shows/characters who try to achieve this but fall a bit short? (a specific example isn't coming to mind at the moment, but it's Monday so my brain is weary)
