When exactly is a Last Stand checked when damage cards cause more damage or fear?

Question

Accepted Answer

Only after all damage and fear from that source has finished resolving, including cards that discard themselves or add more. If you are back under the limit by then, no Last Stand happens. All damage from a single source is suffered before the limit is checked.
