[Tony hears the excitement and "leave the walls" and he knows immediately that this is going to happen. Not only that, but if Hiccup is as interested as he is in developing proper armor, they might just have a chance of creating something he can use again. Wouldn't that be nice?]

Magic armor? You know, I'd normally say it couldn't be done, but with more of us working on it we just might be able to pull that off. And maybe we can get that sword of yours an upgrade too.
