Grimm continued looking for the sniper but had no luck. Looking around he had seen some kind of chaos form, though he seemed to be winning the game. When the disorder had occurred a few people attempted to aid others. He dully noted the boy arriving to the side of a police woman who had been injured. But a more important significant events were happening. A man had run in and started choke-holding many of them to Pacify them, not exactly killing them but he was receiving help and he would have to thank him later. 
A more interesting event happening caught his eye, a small girl had stood up and started to speak. 
Her words seemed chosen carefully and precisely. Criticizing the actions of the terrorists and Connectors, mainly himself in Grimm's mind, probably attempting to change the minds of those who have used violent methods. Grimm was listening but didn't truly care about a fair judgement. Or allowing disorderly chaotic people live, he would never compromise with such people.

One line stuck in his mind. "Slaughtered like Sheep?"
No... Do not compare an animal and a demon.... 

Grimm still was open to her perspective though, when he plunged his knife in one of the closest terrorists it was in a non-lethal area, he then left it inside of him. Grimm absorbed the speech but had already pondered such ideas of eternal punishment and afterlife. He did not really believe anyone would miss him if he died. He had shrugged it off. It didn't faze him in the slightest.
The man who led the terrorists walked to the girl, the men attempting to pacify and defeat him stopping. He froze and observed. When he touched the girl's hand is when Grimm placed a hand on his longsword. 
The man lowered his head then raised it again. A hatred in his eyes Grimm had while fighting his men. He proceeded to unsheath his normal blade when the man spoke of his dead family. He started to stride towards him when Marcus aimed the gun at Eclaire. 
He swung his blade around skillfully, slicing straight through a few terrorists but being incapable of really enjoying his new play things. They were indeed boring. Their leader seemed to be the interesting one. 
He came within 5 yards of him and turned his head towards Enrico. He shook his head as if telling him to not fire, at least for now.

He started to speak to Marcus. Hair untidy as usual and his yellow eyes wide. Shirt covered in the blood of a few of his comrades
"I do not believe you understand the situation you are in right now. Thoughts of dying by my blades would be the thoughts of an optimist. Do not think I will relieve you of your pain, I will not kill you. But murder that girl and I will kill all your allies, and you will only think of returning to your vomit like the dog you are; because I don't let sinners like you go without your punishment..." He could not be taken seriously no matter what way he said it because he looked ready to laugh the whole time, not taking himself seriously. Dealing with this man was a joke. He also seemed to just want to kill Marcus, despite what he said. His hand on his face, his eyes peeking through the cracks made by his fingers, laughing. He was wielding his sword in some kind of drunken fashion waiting for a reply. This boy is a strange one.
