Time travel leads the crew of Deep Space Nine back to the era of Captain Kirk and Mr. Spock, for a stellar episode featuring a return to a landmark episode of the Original Series.

It's one of the best remembered, and revered episodes of the entire series. Paul, Bill, and Andrew explore the epic crossover you never thought you would see.

A special episode of Deep Space Nine calls for a special guest. But, that guest wasn't available, so J David Weter jumped aboard... and, he isn't leaving... awkward.
