What was Worf able to do roughly a third of the way through the third season that would not have been able to do a mere seven episodes later.
So to rephrase the question... Worf did something during the 7th, 8th or 9th episode of season three, that he would not be able to do 7 episodes later. What was it he did that 7 episodes later he could not & would not be able to do for a long time?
Man... I'm stumped. Allow a Romulan to die, like he did in The Enemy
