It also would have made for an interesting two-parter to have the E-D be sent on a mission to retrieve this old Federation POW and realize it was Yar....
I've often wondered if Sela would have worked better if she actually was the alternate Yar herself - who had either been broken by the Romulans or willingly defected to their side.
What are your opinions on Sela? Like her, hate her, what and why?
BRAVO BARVO to the Idea in BOLD
