I think having him need to rely on anyone is a joke. Isn't his whole thing that just because he's deaf doesn't mean he's any different than anyone else? He doesn't need to rely on anyone else to help him. Ridiculous. It kind of seems like the whole show is making him into inspiration porn which, as far as I can tell, goes against what he is trying to accomplish. He's a great dancer, just let him dance. There are definitely plenty of people in the world who do need to be shown that someone who is deaf can do whatever they want so yes his visibility on the show is fantastic! And not just for ignorant hearing people but for deaf people as well, like my boyfriend. We have been taking ballroom dancing lessons together and I think he loves seeing someone he can relate to on TV! Representation matters.
It doesn't surprise me in the least that the show would stoop to the level of gimmicks, but they are really doing a disservice by doing that.
