Obi-Wan/Ahsoka Palpatine was the Sith?!? If we didn't sense that then the Order truly had lost our way. Right under our noses all this time...
You can't trick someone into falling to the dark side, Ahsoka. They may not realize that's what they're doing but it takes deliberate action.
That's kind of you to say though, I do appreciate it. I was hardly the ideal teacher at the beginning, when he would have needed me the most. It was my master's dying wish that I train Anakin and I was bound and determined to do so, even if I had no idea how.
