Are we not supposed to like Ji? The way these ep's have been he's less of a teacher and more of a douche, why would you take something that isn't your that was made to help the team out? It wasn't like he hurt one of the rangers during a fight Gold's just very cocky. one other thing are they going to keep that "lets rewind Gold's movements thing"? At first it was cool the second time not so much
The second rewind thing is the last you'll see of it.
