That’s my understanding. Dean even mentioned that her voice sounded strange when she brought the provisions.

I have to admit that I’m losing faith. Real Lottie still hopes that everything is fine. If she went to the police first and went to Dean’s flat accompanied by the police (before Evilottie/Beate calls the police, to have them arrive very shortly after real Lottie would arrive), there might be a chance for survival and catching Beate. But as things went on up to now, at least as much as we know it…
