Well you know who it is. The worst part of being GL is that people tend to think they know more about the SW universe that himself, the creator.
It has to suck...
Totally true...
Anyways, in the novel Yoda and Obi Wan weren't fooled by them.
I decided for fun to make a pic of what they might look like sitting around the Jedi Council chamber, waiting to see if any stragglers might come in. Not the best pic, but kinda mimicks the tone for what I think GL was going for in the novel.
