Where did anakin find the time to get a thesaurus between the beginning of Ep 3 and the end. Throughout all of Ep 1 and 2 and the clone wars he spoke like a normal dude. Suddenly he's all "You understimate my power" anakin Skywalker?????? I refuse to believe he knew what underestimate means.
He got so confused when Dooku talked in Episode 2 that Obi-Wan got him word-of-the-day calendars during the whole Clone Wars.
