This guy’s Mustafar test from the radical redux thread is amazing.
Hello There! here is an unfinished test to place the battle of Mustafar in TLJ, I have an idea behind my head with the voice of Vader, so that he guides Kylo to him to link the line “finish what you started” with the he story of Palpatine pulling the strings, to me it is more important that this revelation is made just after the death of Luke.
