- Fridge Brilliance: In the first poker game depicted in the episode, Dr. Crusher calls Riker's bluff. When Riker asks how she knew he'd been bluffing, she says that he had a tell with his left eyebrow. However, she's only kidding. So how did she know? Perhaps she just "had a feeling," thanks to having already been through the time loop a few times, but not enough for her déjà vu to have registered yet. Since it's the Enterprise's twelfth trip through the loop, it's probable that during the "original" poker game, Crusher never called Riker's bluff.
