Petron ignores the little girl for now, he knows she's a witch, even if she claims she's not, and Erik says that's "normal". The heck with their definition of normal! If she brainwashes you with her eyes, she's a gods-damn witch! His thoughts occupied, Petron seems lost and distant, quite different from his usual cheerful self. Even Amica doesn't get the attention she was expecting, or fearing, she would receive.
