I doesn't bother me that Sarah didn't guess Riley was a time traveler. Confronted with evidence that Riley knows something about Judgment Day, which scenario sounds most plausible:
1) My teenage son opened up to his girlfriend.
2) The girlfriend is a time-traveler with a secret agenda.
Occam's razor kind of points towards a teenage boy talking too much to his girlfriend.
