Matt is starting to look angry, its obviously not in Gray's best interests to push him around. "Look, I don't trust you. I know what you are yes, but that makes me want to help you less, not more." He says glaring at the older man.
"I am surprised you haven't put it together yet, observational skills must not be up to snuff. Pretty bad for a Watcher. My father was pretty famous on the council, you must have heard when he left. Since he didn't have a Slayer to train, he trained me." he takes a deep breath to calm himself before continuing. "I'll do what I can to make her ready, but for her sake, not yours. Just go back to England."
He looks at the teacher for moment before heading off in the direction of Gwen and Mercedes. When he finds them he still looks angry, but also his face shows some concern. "Are you girls alright with allof this? I know its a lot and will take awhile to accept. I'll answer any questions either of you have."
