As Messer walked into DADA classroom, he saw Professor Romanos was sitting in lotus position "Hello, Professor. How's your summer?" he greeted the DADA Professor with a smile then his eyes went from Professor Romanos to another Professor who looked like he's hit by Full Body-Bind Curse? The figure on the floor look like the new Astronomy Professor but the fourth year wasn't so sure should he greet him or something? Maybe its best for him to greet the man later when he's awake for now he need to find himself a seat.
