Sebastian stepped forward towards the door when he heard what sounded like a thud on the other side of it. Reaching out to touch the knob, he was surprised to find that it was extremely cold. Remembering what happened to the other door, he was suddenly afraid she would try to lock herself in again. Or, it could have been an accident. Either way, he now knocked on the door.

"Are you sure you're okay?" he asked, but realized that she probably didn't want to talk to anyone right now. She was probably afraid of herself and what she was capable of. He wanted to try and comfort her somehow, but he wasn't about to just invade her privacy and teleport in there like last time. With a sigh, he looked up at the door again. 

"I understand if you don't want to see anyone right now. It might be scary now, but this place can really help you. I mean, it helped me." Sebastian took a step back from the door and turned to leave, but decided to say one more thing before he left. "Don't be afraid to be yourself here. Everyone here's been through the same thing. But if you need someone to talk to, you can always talk to me." With that, he started to walk down the hall to find Melissa's office. Grace needed help controlling her powers, at least so she could get out of that room. She would know what to do.
