How do you complete flitwicks task on Harry Potter and the Order of the phoenix wii?

Answer 1

One flight of stairs up (not a level up) will be a portrait if you talk to it it will let you through - it might tell you to find the other side of it first which is on the seventh floor same area as the room of requirement. Then go tell Hannah to go through that.

Answer 2

You walk up the stair case in that same room and talk to the picture on the wall. Then walk back to Hannah abbott and talk to her. That is it.
