In the new issue of Time magazine, there is a picture of that blue Twi'lek Jedi with a blue lightsaber. Intrestingly, her name is given as Aayla Secura. Just a piece of information I thought you might like to know.
Also, in a picture of many Clonetroopers similar to the ones we've already seen, there can definately be seen some with colours of red, yellow, green or blue on them. I never realised there was that many different colours, like a rank system.
Just bits of information I thought you might like to know...
