Is the redirected lightning not as strong as the original lightning?
I ask because, for example, in the end of The Search Part 3, when Zuko redirects Azula's lightning, it actually hits her, yet not even her clothes have a burn. So is the redirected lightning not as powerful as its original lightning, or was Zuko, since he tried to help her as she ran away in the end of this same part, lowering the power himself when he shot it back?
