Obi-won and Yoda's return to the Jedi Temple
When Obi-won and Yoda went back to the Jedi Temple and had to change the code to warn other Jedi that it was dangerous to return to the temple, so how come they were there in the first place if it wasn't supposed to be safe? Wouldn't they have thought twice about it going there? So why were they walking around freely if it was supposed to be dangerous?
Since they were able to walk around freely anyway, shouldn't they have issued a "code clear" or something?? Like, just to prove that the Jedi aren't cowards?
