Their eyes widened even more at the rather nonchalant way I mentioned that their door was a lot easier to get through than the others. Honestly, they were all easy. Ravenclaw was a puzzle. Hufflepuff was tapping the right sequence of barrels. Gryffindor and Slytherin had passwords, but had other ways to enter. Like Gryffindor, you could stare down the portrait in a challenge. She would eventually break and allow you entrance. Slytherin had the Parseltongue entrance.
