What is the outcome of a flash forward sequence?
A.
The events depicted may or may not happen.
B.
The events depicted are definitely going to happen.
C.
The events depicted may happen, but with a few certain changes.
D.
The events depicted may happen, but with a lot of changes.
A flash-foward shows events in a narrative/story that are happening (going to happen) in the future, one way or another. Therefore, it seems logical to assume that the event will "definitely happen."
