Why was this woman so persistent? It's one thing to want to help, but she is deliberately standing in Penny's way. He was getting bad vibes from her and that genuine smile caused him to feel even more on edge. 'How does this woman know about this witch...' The question rung through his head as he tried to figure out where the witch was. They were in a trap, that much was clear but where in the world was she even hiding? And that's when it hit him harder than getting hit by a train. This entire time he smelled something off, something that his body made to counter the God's themselves could pick up. It was the scent of blood. He must've not been able to smell it due to the different scents of people in the station but now it was close. It was coming from that woman. 

This is the worst place possible to find the blood witch. A train station filled with people is like an unlimited power source for the woman but he couldn't shout for people to evacuate or else he would make things worse. That's when he decided to do this; he created a cloud of ash that he made it appear that it came from the train. People were coughing and gagging so in order to breathe they were starting to run out of the station.
