Before the screaming happened, Ash was having his break and kicked up his feet in an empty class room, he was going over grades homework and other class work, going through most of the work Ash found something that really annoyed him, Maya's work, he didn't really see anything for her and the little that he did see of her work and homework was severely lacking. 

Ash slammed his fist into his desk and stood up he was gonna look for her and force her to finish her unfinished and blank work and homework on his desk as he went out to get her to finish everything she was missing, after asking a couple of the other teachers where Maya was it wasn't long before he was walking towards the stair well. 

As he went to the stair well heading to the roof he could've swore he heard someone screaming, but he shook it off, feeling as his nerves were getting to him, he must have been having a long day and thought he was just hearing things, the climb to the roof during the stair well was just cut short when Maya came running down the stairs and ran face first into him, he stood still and looked at Maya with a clear look of anger on his face. 

" [color=ed1c24]There you are ! How many times have people told you not to go the roof, huh ?! I willing to over look chilling out on the roof if you come back to my class and finish off this work I gave you.[/color]" He told her. He didn't know what was going on outside and wondered why she was running for a second, but then he just put it off and kept glaring at his student wondering what she'll say.
