wheeljack really screwed over the autobots in season 2. he revealed in hurt that he spent his time on earth scouting decepticon mines. at any point did he report these mines to the other autobots. y'know because it really could have helped them. in hurt, he clears a mine of its guards and simple blows it up to get megatron's attention. he could have reported the mine to the autobots so they could grab some much needed energon before more cons arrived. wheeljack could have at least taken some with him. but we have already seen that he doesn't really see the big picture.
