I honestly don’t really like it happening at all, but I’ve accepted that it will. I think it’ll reduce the significance of their duel in ANH, but perhaps they’ll spin it in such a way that provides more substance to that or to other moments in the OT. For example, perhaps we’ll see how Ben came to completely lose hope in Vader ever being redeemed (as he says to Luke in ROTJ)?
