Rey’s identity is yet to be revealed. Rey has been said to be a Skywalker, a Palpatine, or a Solo. The most promising theory is that she is a Kenobi. First, take a look at her attire. Her Jakku clothing is very similar to Kenobi’s Jedi robes. Jedi can choose what colors they use so Kenobi’s is unique. Second, when Rey touches Luke and Anakin’s lightsaber who speaks to her the most? Obi-Wan. After she leaves her vision you can hear young Obi-Wan’s voice whispering, “These are your first steps”. Why couldn’t it have been Yoda or Anakin? There’s a reason why Obi-Wan made such a big appearance in her vision. Obi-Wan was in possession of that lightsaber longer than Anakin and Luke combined. Third, she used Jedi Mind Trick without any training at all. Who else is incredible at using Jedi Mind Trick? You guess it! Obi-Wan Kenobi. Kenobi was no stranger to breaking the Jedi Code for love. In the Clone Wars, he had a secret relationship with the Duchess Satine of Mandalore. She was killed by Darth Maul. During his exile on Tatooine, he could have had a child with a someone. Hopefully her identity will be revealed in Episode VIII.
Rey uses a staff as her weapon on Jakku. That could mirror a double bladed saber staff. Her color? Yellow. Kylo Ren’s lightsaber was from an EU character named “Darth Revan” who was the Dark Lord of the Sith in Knights of the Old Republic stories. He too, had a crossguard red lightsaber. Why not also use the Jedi, Bastila Shan’s lightsaber as well. Yellow lightsabers were used by Sentinel Jedi. Sentinel’s weren’t always strong with the Jedi Order and often consisted of Grey Jedi. Grey Jedi were Force users of the dark and light. They believed in balance. The only known canon Grey Jedi are Qui-Gon Jinn and Luke Skywalker. Qui-Gon often defied the Jedi Council and Luke Force Choked a Gamorrean Guard at Jabba the Hutt’s Palace. Rey may not be a Grey Jedi since she is supposed to be a symbol of pure light and the anti Kylo Ren. If she isn’t yellow, she’ll be blue. Hopefully she’ll make a lightsaber in Episode VIII.
