Most likely, and this is going off many ln/wn I read, there was quite a bit more inner monologue or narration likely carried it and the artist doesn't have the skill to draw the narration.
what likely happened was "Im slammed, I cant just bump you to the head at a friend discount and I don't want you to pay normal prices"
"Oh FUCK no, you treat your weapons like THAT and expect me to make you something?"
then after holding it in her hands/seeing how it broke realized he is something special
"Scratch that, I will make you your new weapon, it would be an honor"
the ln/wn may even have a special chapter to this character's inner monologue as this interaction plays out.
