The Legend of Korra

But still, vibrations travel through metal too and should be able to be sensed too. Depending on the rate that vibrations travel through differnt materials, maybe even better sensing. I just find it weird that a senser gets surprised in an episode when she should have at least sensed someone was coming, while a non-senser (Tenzin) just turns around and owns the guy. I mean Toph could sense, although the view was fuzzy, through sand, but she could still sense something at least.

Since he's an Airbender, he could have easily been alarmed by a change in wind. The fact that it effected his mighty stache could just be an effect. Honestly, we don't know what kind of senses Airbenders have in terms of air movement, they could have skill similar to Earthbenders, but with Air.

Am I the only person not that bothered by the fact that they reused the voice actor? I find it strange, but I am so excited that Iroh entered the show that I can move past it. I hope he inherited his family's power and technique, while also having Uncle Iroh's sense of humor (too much to ask, I know).

I like the idea of Iroh, and the fact that Zuko honored his uncle with him, but to use the same voice for two major characters is stupid. When it's minor characters you can get past it, but it's a big deal with major characters. It honestly threw me out of the show for a bit, because that kind of reuse throws realism out the window. It's like when TV Shows reuse the same actor for characters. If you've watched the entire show, it throws you off and destroys realism because you KNOW that person was also someone else, who was completely unrelated. It's like they needed someone last second so they called someone random on a list of people.
