[Keith might not regret it but a small part of Shiro does-- Keith's an amazing pilot, after all, talented and breathtaking and it's a shame they don't recognize it. And an even smaller part of him regrets that he wasn't there to try to keep it from happening. But still, it's Keith's choice and path, and if he's happy with how things went then... well. He can't regret it too deeply.]
[He chuckles a little, all the same.] Guess it fits the whole lone wolf image, huh? The cool, talented rebel too independent to listen to anyone's authority.
