Because of the 1988 Writers Guild of America strike they had to shoot this episode in 3 days. It's pretty much crap, consisting of repeat cut + pasted clips from Season 2 and was described by its writer, Maurice Hurley as "terrible, just terrible."

Why the producers couldn't just wait to shoot something decent who knows. I'm guessing because of the strike the production ran out of money and could only release a flashback episode or maybe Roddenberry was too sick at the time to be able to veto this half-assery. This episode also marks the final appearance of Diana Muldaur (Dr. Katherine Pulaski) on the series.
