I like the idea of the stranger being some long-time nomad who just wanders the rim helping struggling survivors get on their feet and then leaves after they've helped stabilize the situation.
Making them a temporary colonist who disbands after some set conditions and cant have their gear taken off would be a better way of implementing it.
