Of course Sete had seen it, how could he not see it if he had attended that race for the simple fact that it was the first time you had raced after a while (you decide whether as a wildcard or because of some accident), but you seemed to be fine, after all you had risen practically instantly from the ground.
The thing changed when you returned to the box where he was waiting for you and when you took off your helmet you could see the wounds that had formed on your neck and face just a few minutes ago, that of course caused Sete to approach you almost instantaneously.
โYou told me you were going to be careful!โ He said grabbing your chin to get a closer look at the wounds โYou know what it means to be careful? Because this isn'tโ you could see his concern as he scolded you.
