Why would the Emperor’s royal guard be protecting Vader though?
I think that might actually be the emperor…
And if it is who or what is he kneeling to.
There is nothing to suggest that he is kneeling before another person here.
It could be that this tube thing is some sort of Tech to do with the Super Laser on the Death Star and they only just cracked the formula to make it work.
I have also heard a rumour that All the Bounty hunters from the OT will make an appearance but they were not chosen. Jabba may also be in it too. Forest Whittaker is a bounty hunter and is hired possibly along with some of the others. Not sure if it is true but there you go.
Cad Bane is also added to the bounty hunter troop
Not sure about him hope he looks better than that.
