FlashForward – My Own Personal Mosaic Project
We don’t know yet whether the future that they see is true or inevitable, but as the series progresses, the various characters seem to pulled in the direction of what they saw. (A recent episode upended all that when a character who did have a flash forward killed himself, though.) Whether this is because they’re locked into a predetermined future, or because they subconsciously direct themselves toward what they’ve seen is a valid question at this point.
