I think the last thing Tomas needs to be worried about is his loyalty to Basamak. I know reading manga sometimes requires a suspension of disbelief, but as someone who hunts with archery, this is just too ridiculous. Tomas would probably not even be alive, let alone be able to walk around and talk. Arrows don't just stick in an object when they get shot. Unless they hit a bone, there's a good chance it may fully penetrate the body. And if it did strike a bone, it's likely the bone would be broken or shattered. Even just a "flesh wound" arrow into the shoulder would cause an immense amount of bleeding. Tomas had at least 6 arrows sticking out of him, including in several vital spots. It's possible he'd still be alive at that point, but he would be in extraordinary pain, and likely bleeding out at that point.
