Galvin

Galvin smiled and said, "That's nothing. I'm glad your grandson is all right now. A mediocre potion master cannot save him after all." 

As he heard the old-looking dwarf and Galvin's conversational exchange, Saeara's face turned from hostile, confused, to being stunned.

"What do you mean?" he asked desperately. In that instant, he knew that he had to learn what Galvin meant by saying what he said. 

Galvin knew how this could kill someone, and did not change his facial expression on purpose. After observing the old-looking dwarf's appearance a little, which hadn't really changed, he stood up and looked at Saeara. 

"Oh, my apologies. I should not have said that, right?" Galvin said, putting his hands to cover his lips.
