Edward simply ignore the remark but spoke as he walked into the Academy. 
"We shall use the Spiral Staircase. All things are sentient in this Castle. If you misabuse something too many times or the item decides not to like you for some reason, you will not be able to use it if you get my drift. To use the Spiral Staircase, please your hand on one of the railings and ask it to take you where you want to go. If you do not move, the Spiral Staircase has either been offended by you or you are not allowed to go where you asked to be taken. Please follow me.
To the Students Bedroom Floor, please."
