After saying those words - Wellings' eyes felt like they've seen the ghost from the past and not just ghost, however - more like monsters that were crawling up in the window trying to eat him up. That's what he's currently having a vision and he was about to shout and stumble on the ground when Giovanni immediately hold his arm on one side as his other hand covered the old man's mouth. There - he made the old man face Heil - who was already looking at him like a snake - who'll eventually bite him the moment that he move or even speak the wrong words that Heil wanted to hear. At that very moment - the old man's body began to shiver again until he can only calm down - with such a look Heil was portraying yet the words that he had heard earlier from the latter were such a horrible scenario for him to even remember - yet he had no choice but to say those words - or else the man that was behind him was already holding his neck
