I liked the UK comics story where Horde Prime originally split the power sword, with He-Man getting one half and Skeletor the other. Then when I heard the movie was using the mini comics two power swords idea, I immedieatly set about trying to figure out how She-Ra would be able to exist in a way that is still true to her origin. I reckon when Adam unites the swords of Light and Darkness in the new movie, releasing King Grayskulls power and becoming He-Man. The sword of darkness could also be changed at this time to become the sword of protection. Basically She-Ra would inherit Skeletor's sword, because like the Sword of Darkness, Adora also would have come from darkness (serving the horde) into light. Just an idea!
