Although Tag hadn't answered, when Botros came to his side the little blonde still got a little reassuring pat from his Professor. Stopping for a second from drawing the Algiz rune Tag looked up at the nice, old Professor and smiled at him.

Continuing to draw Tag stopped after a few more practices and looked up from his desk. Excuse us! We have a class going on here, Suits of Armours! An they were knocking things over from the students desks. That wasn't very nice. MANNERS!

They had something to do with what they were learning in class today.

"Well, like you said earlier Professor, Heimdallr provided protection and was watchful. Maybe the reason for the Suits of Armours fits into class because they could protect the castle? Didn't they do that already, protect the castle once?" Tag said with his hand up. Obviously they could protect the castle, seeing as they were moving about this very moment, when Tag thought they were only stationary. Though, if they were going to protect Hogwarts could they be more careful with their spears?

How they connected to the Algiz rune, Tag couldn't put his finger on that. Suits of Armours couldn't possibly interpret runes. Could they carve onto the Suits? Tag highly doubted that option.
