because of the 1988 writer guild of america strike they have to shoot this episode in 3 day . it pretty much crap and consisting of repeat cut plus paste clip from season 2 and be describe by it writer and maurice hurley a terrible and just terrible . why the producer couldn not just wait to shoot something decent who know . i be guess because of the strike the production run out of money and could only release a flashback episode or maybe roddenberry be too sick at the time to be able to veto this half assery . this episode also mark the final appearance of diana muldaur ( dr. katherine pulaski ) on the series .
