The way I look at it is that Impulse going back to the past, saving Flash, interacting with Jaime, and everything else has created a new timeline. I don't think there is a paradox because there will be no further interactions with a universe in which the aforementioned events did not occur. Based on the events of this episode, barring any further revelations about the scarab I believe that Jaime's fate has changed permanently. Of course, that raises the question of why Neutron in the future only witnessed a partial change, much less a change at all (if a split in the timeline occurred, why would he be affected at all by changed events in a parallel past).
