6. The Blue Ghosts
So, will Luke be talking to his Dad, Yoda and potentially a made up to look more like Alec Guinness Ewan McGregor Obi-Wan Kenobi on a regular basis in the sequels? I always saw the ghosts as only there when they had parts to play in Lukes journey. Sage advice at key moments and what not, as opposed to on demand call up for advice type of stuff. Additionally how much does Luke really want to listen to these guys when it comes to the future of the Jedi order, given what came before? I would almost 100% guarantee the blue ghosts are going to show up in the new Star Wars sequels but it will be very interesting on what capacity. Lucas used them very well in Episodes IV to VI and used the prequels to signify their importance to the Jedi order, showing their path to discovering this ability. In Episode VII I would guess we will gather a deeper knowledge of what the blue ghost state of existence is, what it can be used for and of course still offer up those moments of wisdom when Luke so desperately requires it.
