§10.6. More general linkages
We are allowed to link the beginning or end of any scene to the beginning or end of any other scene. So, for instance:
Luggage Trouble is a scene. Luggage Trouble begins when Brief Encounter begins.
Thus the two scenes run concurrently, at least for a while. We can also add that:
Luggage Trouble ends when Brief Encounter ends.
This can be useful when a large, complicated scene really contains several smaller sub-scenes.
A special exceptional case is that we can have any scene or scenes starting right at the outset:
Railway Meeting is a scene. Railway Meeting begins when play begins.
When play ends, of course, all scenes end, so there is no need to say that.
