Sebastian was watchung the ordeal from above, having left the girl, Jasmine was her name, at the apartment to pack her things. If he wasn't able to get her later, he'd told her to head to the Reformist HQ, were he would be waiting. Then he had leaped into the battle, easily bypassing barricades as he sought to find Isabella, eager to make the bitch scream for thinking she could lock him away with no consequences. 

He stuck to the shadows, slithering through the compound to Isabella's quarters, silently killing any of her mutants that took notice of him with a bloody tendril right between their eyes. He soon approached the room, slowing his gait slightly as he opened the door, a dark smile on his face as he saw the object of his vengeance. 

"Why hello there, Madame Isabella, I see you've become even more beautiful sincd I last saw you. I'm going to enjoy taking that from you." He said, two tendrils of blood fotming on either side of him as he approached her, his gait casual and calm. He was in control here, and he wanted to make sure she knew it.
