Yoda is exceptional in this arc. It is easy to give adventures to characters like anakin and obi wan as they have flaws despite having good intentions. But Yoda is old and wise and until this arc has come off as a flawless character. Yet this episode proves not even yoda is flawled, he too has the dark side within him. And he battles with it. No seriously. I mean he LITERALLY BATTLES WITH IT. This episode is so good.
