While it has the potential to be angsty (seriously what doesn't these days?), I don't think it would be too angsty actually. Unless of course I wanted to take it in such a direction (which I tend to lol).

He grew up mute, so it's just how he lives, so it's not a big deal. However, now he has this opportunity to speak, and that would be very emotional I imagine. I...also just realized isn't there a news story going on like this right now? XD I should read that, because it sounds amazing. That aside, yeah, there's the angst possibility, but if you keep to Danny's upbeat attitude for the most part, it's more like a puzzle or problem to work through than something to be emotionally painful.

Then again I like angst so let's just go with that. :p
