I mostly meant that we know who all of the actors for the original Knights were and they were all male, and also that none of them had the darksaber.
We also know that the original “actors” weren’t actors so much as stand-ins for later.
Also, no one knew that Moffat’s Gideon had the Darksaber until he pulled it out. It’s quite portable. Also, who knows, maybe she didn’t acquire it until sometime in the years between that flashback and a year after TFA/TLJ takes place.
I just feel portraying it as an impossible plot hole is a bit much.
That’s a valid point.
That said, the scripts do not make her feel like a very good villain, haha.
