With the permission of YourSecretWeapon, I shall take on the role of Serena (previously an NPC).

What is your full name? 
 "Serena Vermont. You probably know my-"

How do you look? (You find this a strange question but decide to answer it anyway) 
 "Well, that was rude. Anyway, I am blessed with the same good looks as my mother: blonde, blue eyes, long legs."

Describe your personality. Be honest, I will be able to tell if you lie to me. 
 "I am pretty sure that I have the right to not answer any of your questions. Naturally, I'd like to cooperate on administration at all times. 
 Consider me... a friendly lady with a tad of mystery."

What house are you in? Do you feel you belong in this house? 
 "Slytherin and lovin' it. I would just die if the sorting hat had even considered Hufflepuff. No offense."

How is your O.W.L. and/or N.E.W.T. progress going? In other words, which classes do you specialize in? 
 "I am not sure how valuable these classes are to me, but it is a hardcore fact that I am an amazing student. 
 My grades were simply outstanding for Potions and Transfiguration. 
 I even scored exceed expectations on Muggle Studies. Can you believe it, boring old Muggle Studies? I suppose no class is too hard for me to master."

Do you play in Quidditch? 
 "Good heavens, no. That is such a rough sport, I am perfectly fine cheering my brother on from the sidelines."

What does your Patronus look like? 
 "A pretty fox. You should see it, it's adorable."

Do you have a pet that stays with you? 
 "Yes, I do. But mother is sending Lady to me tomorrow. She's my Chihuahua and she doesn't like train rides at all."

What are your most used spells? 
 "Accio gets dropped on a daily base. Isn't it just super-useful?"

During the entire interview, Mrs Raspberry couldn't help but wonder if Serena was being sincere about her answers, despite the fact that she claimed to be able to tell if she would be lying.
