Obi-Wan had other things on his mind, more pressing matters than some minor flesh wound. This particular battle required more of his concentration and skills than normally, but even he had not foreseen the sheer size of their opponent. The Separists had been expecting them, something that worried him. It was with calming himself through the force that he was able to keep focused through the battle.

They had been separated, as was expected in a battle of this magnitude, but he senses Anakin's presence there and all his worry before he hears him speak.

Obi-Wan finally took in his own injuries, but as usual, he downplayed it. "I'm fine, Anakin," he reassured the other in a calm voice. But it wasn't the absolute truth.
