Rudra and Thor both observed the fight of the kids closely from the stands.
It was one of the rare occasions when Thor was not shouting like a Viking, but rather calmly observing the fight like a true spectator.
In Rudra's point of view, Sebastian had cleaner attacks, a faster speed and superior strength, however, for some reason the kid was holding back his power.
While his " Sword Dash" attack was too fast for most of the audience to see, Rudra and Thor could see such slow attacks as clear as day and they noticed straight away that at the critical moment, Sebastian diverted his attack to Nick the side of Max's stomach, instead of piercing straight through.
Whether it was his friendship that got in his way, or whether it was just his soft nature, Rudra did not know, but what he did know was that unlike Sebastian who went easy on Max, Max fought like a hungry beast.
