They were obviously talking about Lucy(Magic commander).While it was a good fight, I can't help but feel a little baited by the chapter name "Old man, into a bloodbath!" when the old man is shown for all of one panel, and we hardly even see his fight.
If the sorcerer grandma was correct, the dude was just a random thug of a little bit of strength, who was given all the fancy equipment as a plot by someone else. Often those who didn't really work for their achievements are the most arrogant ones. If that thug had beaten the magic devouring wolf himself, he probably would have had a much better understanding of his own gear's strengths and weaknesses. However, he was just a hoodlum who was probably told he would be invincible wearing them.She beat that man with his trauama. Imagine getting some strong ass ability that most people in your world wouldn't be able to conceive of or beat, and then someone just overwhelms you and to add insult to injury, brings out your dad's belt to beat your ass.
