It was quite an understatement to say that Hal's words dug up old wounds and they were far from being memories Gregory wanted to remember.
However, looking closely at his situation and how much thought Hal had put into trapping him and making it so his only means of escape was a fight to the death, he had to admit,
Yes, it truly was fitting.
He was far from being overconfident.
From what he had heard of San and Hal's battle (which was not that much) while Hal had been able to hold out against the much stronger man, it was only due to his implementation of Runes.
Then again, the little he had heard had been fed to him by Burt who had 'gone out to source for information', and could all have been lies to make him lower his guard.
