Michael hated this, hated that even during the day this couldn't be a safe place for his daughter and it made him want to leave the castle all together. It could have been her just as easily as it was the girl who did find herself on the wrong side of that curse. And so he waited for her at the top of the stairs that afternoon. No where was safe in the castle, but having Wren with him made him able to breathe a bit easier.
Of course that she was with the Weasley boy before she came up the stairs was less than pleasing even if it meant that Wren wasn't walking the halls alone. And seeing him kiss her and hold her close even less so.
Thankfully though the boy wasn't a complete idiot and left before he decided to take further advantage of his daughter before he left. He wrapped his arms around her and lead Wren into their rooms once she reached the top of the stairs. "Monday he has lots to teach you?"
