Fight The Dragon.

The weak can think as much as they want and have opinions about everything but it wouldn't matter. That is not so for the strong. The opinion of the strong matters a lot. 

If he were prideful and foolish, he wouldn't take the advantage that has been offered by attacking first. Unfortunately or fortunately for him, he is anything but full of pride right now. That blow to his pride made sure that he is lacking in pride right now.

So he made the first move. He grabbed hold of the gravitational field of the dragon to control it. He pulled on it and found it to be immovable. It stood unaffected and resilient to his manipulations like that of a fortress. His own gravitational output and influence over gravity are not strong enough to overpower that of a dragon that has been empowered by the power of the world.
