When Obi-Wan and Anakin chase the assasin person into the pub after chasing her through the city, Obi-Wan leaves Anakin to get a drink and tells him to find the person who tried to kill padme. While anakin is walking through the crowds and suspense is rising, notice his padawan braid. Usually, the Jedi apprentices wear their braids on the right side of the head, but you can clearly notice that Anakin's is on the left side, as it has been for the movie leading up to this scene, aswell as the scenes preceding this one.

if this was supposed to happen, then im confused, thats for sure.
