As an aside, red lightsabers were not a symbol of the sith at this point in time. In fact, every Sith Lord prior to this used either blue or green.. in one case orange (being former Jedi), or swords/staffs and the like.<br/><br/>Also, I had an elaborate idea about Merryn using mind trick but then I thought it too fancy and just did something simpler. Turns out this simpler idea is way better- and more philosophically symptomatic of the Revan in her. ;)
