At first Magnus wasn't even sure that the woman was addressing him but when he turned and caught her gaze he realized that she had, indeed, just asked him in halting awkward German whether he wanted a candy. He raised his eyebrows and regarded her for a moment before he asked- in English- "What?" There was clearly some kind of confusion if she'd made such a poor attempt to speak to him in German and all he'd been doing was minding his own business (well, mostly, the building across the street not withstanding).
