Perhaps he raised the question because the prequels turned Darth from a cool name into a lame title.
Why not both? I say we need a sith named Darth Darth.
Funny side notes, doing genealogy, I found that in a certain country, in some parishes, the scribes wrote a local girls name in the books as “Darth” (which is also contrary to all the claims that the word “Darth” has never appeared before and was made up for Star Wars) coming from Darthe or Darte which is Dorothy in English so Darth Vader is really Dorothy Vader 😃. Also amazingly I found farms called Jawa, Tatoone, Tosche, Jaku! Part of me almost wonders if someone he didn’t once see an old church book from this place, although it seems hard to imagine.
I even have a female direct ancestor whose name was written out as Darth in baptism record!
And talking about Darth Darth… that reminds me of the 80s and Mr. Mister which reminds me that I also found in those church books a few Mr. Misters listed.
