Melanie: (Quietly, to herself, her German accented with a slight tremor) "Ach, dieser Ort... es ist nicht sicher. Nicht sicher." (She stares at the photos on her camera, her brow furrowed in distress. Her finger hovers over a shot of the Alborn town square, empty and bathed in the late afternoon sun, but feeling eerily deserted.) Hunter: (Approaching, his voice gravelly and direct, but attempting to soften it slightly for the benefit of the nervous-looking young woman) "Excuse me, miss? Mind if I ask you a few questions? Detective Hunter. We're looking into some recent... disappearances around town. You new here?" Melanie: (Her head snaps up, eyes wide with a mixture of fear and confusion. She doesn't understand a word, but the serious tone and the word "Detective" are universally recognizable. She clasps her camera tighter.) "Ich verstehe nicht. Entschuldigung, ich... ich spreche kein Englisch." (Her voice is soft, but thick with the German accent, and trembles slightly.) Hunter: (He blinks, a flicker of frustration crossing his face, quickly masked by his usual stoicism.) "Okay... right. English. No English. My bad. Look, I just need to know if you saw anything unusual. Yesterday, maybe? Around the festival grounds? Anything out of place?" (He gestures vaguely towards the direction of the recent festival, hoping hand signals might bridge the linguistic gap.) Melanie: (Her eyes follow his gesture, then dart back to her camera, her expression deepening into one of troubled recollection. She shakes her head slowly, then speaks rapidly, her words tumbling out in a rush of anxiety.) "Das Apfelfest... es war wunderschön, ja. Aber dann... dann wurde alles so still. Die Leute... sie waren da, und dann... weg. Einfach weg. Und diese Leere... ich habe sie fotografiert. Diese Stille... es ist unheimlich." (She shivers, gripping her camera even tighter.) Hunter: (He watches her intently, picking up on certain words – "Apfelfest," "weg" – and the genuine distress in her voice and body language. He crosses his arms, his gaze unwavering, trying to glean meaning from her tone and gestures.) "Okay... 'Apfelfest.' Right. So you were there. And something happened. Something 'weg'?" (He attempts to mimic her last word, his pronunciation rough.) "Like... people left? Or... disappeared?" Melanie: (She flinches at his attempt, shaking her head vehemently, her eyes wide with a chilling certainty.) "Nein! Nicht gegangen. Sie sind nicht gegangen. Es war so plötzlich. Eine Minute waren sie da, lachend, tanzend. Die nächste... einfach nichts. Nur diese immense Leere. Ich konnte es nicht glauben. Es ist nicht normal. Kein Mensch verlässt einfach so seine Feier." (She points a trembling finger at a specific photo on her camera screen – a vibrant, sunlit shot of the apple festival grounds, now with a strange, almost unnatural emptiness surrounding the last few lingering stalls.) Hunter: (He leans closer, trying to make out the image on her camera. The photo, innocent as it was, held a stark quality he hadn't noticed in other shots of the festival. He looks up at her, a hint of respect for her distress in his eyes, despite the communication barrier.) "Okay. 'Nicht normal.' Right. You saw something... not normal. And you took pictures. Is that what you're saying?" (He points to her camera, then to her eyes, then back to the camera.) Melanie: (She nods, her lower lip trembling slightly.) "Ja. Viele Bilder. Die leeren Gesichter. Die Panik... und dann einfach die Stille. Die Bilder zeigen es. Diese Leere..." (She trails off, her gaze distant, lost in the memory.) Hunter: (He opens his mouth to press further, perhaps to ask if she could even *show* him the pictures, when his phone vibrates insistently in his pocket. He glances at the caller ID, his expression hardening immediately. He gives Melanie a brief, apologetic nod.) "Look, I gotta go. Emergency. But... I think we need to talk more. You going to be here tomorrow? Same time?" (He gestures to the cafe, then to his watch, hoping she understands the implication of 'tomorrow' and 'same time'.) Melanie: (She looks startled by the sudden interruption, then nods slowly, understanding the gesture about staying. Her eyes remain troubled.) "Ja. Ich bin hier. Morgen." (She repeats the German word for tomorrow, a flicker of hope that they can eventually communicate.) Hunter: (He gives her another quick nod, already turning and walking away, his hand already lifting the phone to his ear, his "no-nonsense" demeanor fully returning as he barks into the receiver.) "Hunter. What have we got?"
