"As expected, Old John is really a Master Gun Mechanic. Hold on. That's not right. From what he said, it seems as if he is not only a Master Gun Mechanic; instead, he looks to also be adept at manufacturing ammunition at the same time.

He had no idea what caused Old John's changes, to the point where he did not know how to continue the conversation with Old John now.
