I have never seen him but a description of him is more than enough to recognise him, by his red eyes, pale almost translucent skin and nose that bears resemblance to a snake. The only thing I think of to do is to stand upon the table and take some sort of fighting pose.  Don’t show your weaknesses, be strong and proud. Be a Gryffindor. I wanted to be sorted into that house, then I better bloody act like it.
