Breznican is certainly a reliable source for information given how closely EW works with studios such as Lucasfilm. If this is accurate, the inclusion of more Obi-Wan raises questions about why he is there or referenced. Episode VIII referencing Obi-Wan would not be the biggest surprise after all. He is the mentor to Luke and appeared to him at the end of Return of the Jedi – and with Luke being the mentor to Rey this time around, him recalling advice from Obi-Wan would be a simple connection to make and one that would excite audiences.
However, if Lucasfilm truly is holding back on an Obi-Wan movie due to the saga films, then something more than a reference has to be in place. Regardless of whether it is Episode VII or IX, Breznican seems confident that McGregor will be making a physical appearance. This may sound familiar as McGregor appearing as a Force ghost in Episode VII was previously rumored this year.
As is the case with any Star Wars rumor, this could be another indicator to Rey’s lineage as well. Audiences began speculating the possibility of Rey being Obi-Wan’s granddaughter ever since he spoke to her in the vision sequence, but there was very little evidence to support the theory beyond this. If Obi-Wan’s role is important enough to hold off a standalone film, the revelation that Rey is his granddaughter is certainly a good enough reason to do so. Now, everyone will have to wait and see if there’s any truth behind that idea.
