I think it's obvious that they're not going to show any kind of closeup on Braig's injuries - it'd be pointlessly graphic. I'd actually be surprised if they show any blood at all. After all, even with the camera pointed elsewhere, maiming a character this badly would probably be hard to get past the censors.
Terra's the only one, in my opinion, whose character would stand to gain enough from such an event to make a scene out of it. His story seems to be based around his growing ruthlessness and single-minded pursuit of his goals, and doing massive irreparable damage to someone who's in the way has a lot of potential in that context. The implied messiness would make it particularly effective for use as a wake-up call for Terra, for example.
