The Plan:

"Roger Davies."

"So tell me about him. I hear they are a dark family but almost every pureblood is. Except the Weasley."

"I don't think he is evil. I can tell."

"Okay. Look for him on the train and bump into him and then say sorry. Start up a conversation a good one and make it long. If he is interested he will want to continue the conversation another time."

"I never would have thought about that. You so deserve to be in Slytherin."

"Thank you."
