"Well, I know that this is a corridor and people walk up and down them," Janice replied abruptly. "That would be obvious."

Janice just don't like people smirking at her. It makes her feel somehow guilty. She looked back to make sure that he was smirking at her, not another person that happened to pass by very silently behind her.

"I was just from the library, trying to find a picture of Dittany, the plant, not the essence bottle. And if you're a Hufflepuff you would know that I was heading back to the Common Room."

Then, it hit her. Aren't the locations of the Common Rooms supposed to be secret? Well, maybe people would know that the Gryffindor and Ravenclaw Common Rooms are located in different towers, Slytherin's in the Dungeons and Hufflepuff's near the kitchen, but nobody would know their exact entrance and/or password except for their residents.

"Wait, you are a Hufflepuff, right?"

This guy's facial features did look like it belonged to a person from Hufflepuff, but judging from the leather jacket he was wearing that reminded her of the midnight-between-alleys gangster groups, it severely doubt her.
