26
When you stand in a doorway and do not yet know if you are arriving or leaving, everyone at the table rolls +together.
On a 10+, the moment holds. It is not resolved but it is held, which is sometimes what moments need. Everyone takes a Threshold.
On a 7-9, the moment passes before you named it. Spend a Threshold, anyone at the table, to name it now, retroactively, in the past tense where it already lives.
On a miss, you are leaving. You have always been leaving. This is not a tragedy. The GM will tell you what you are leaving toward.
