Sebastian was sitting on the roof of the school, looking down at the courtyard where the students were walking around and spending time with their friends. His mind replayed the scene from just a few minutes ago over and over in his mind, until finally he got fed up with it and stood up from where he was sitting. He had to go tell Melissa that he wasn't up for this, being a mentor for these students. Just because he could control his own powers, it didn't mean that he could teach others to use theirs. 

So now Sebastian teleported down to the front of the building where he knew no one was walking and stepped inside the building. He couldn't be reckless about where he teleported, especially if it was inside a populated building where students were walking to and fro all day. The chances that he could teleport where someone was walking were too high to risk. Regardless, he made his way up to Melissa's office and knocked on the door before opening it up slightly and peeking his head through to make sure he wasn't interrupting anything. 

He stepped inside the office, and, despite the fact that she could just read his mind anyway, he decided to say what was on it. 

"Melissa, I, um... I wanted to apologize for what I did earlier, again. I shouldn't have been so impatient to help. I just... I don't think I'm cut out for this. I'm afraid I'll make some other mistake like that and ruin all the progress that Grace is making. By the way, how did she do?"
