However, later episodes establish Casey has a fondness for cigars.

The first few episodes will establish the mythology.

The promising first episode establishes the characters and poses little moral tests, which they pass.

This episode establishes the power and function of the holodeck.

The first episode, "Arrival", established that the person assigned to the position is frequently changed.

The episode "Ayslum" later established iron as another weapon against ghosts.

Thus, where contradictions arise, I have chosen to adhere to what earlier episodes established.

The episode did not establish if this car shared the same government modifications, or if it was one of the store's other vehicles.

Later episodes establish a basestar's ability to "heal" itself of battle damage.

But each episode establishes its own internal logic and, in no time at all, it seems perfectly reasonable that anything can happen.
