[Both easily explained away. George may not be the most romantic of people outwardly but Fred's always known relationships mean more to his brother than they ever have to him. If he's asking after the house she grew up in, he wants to know more about her and her family and the type of life she's lived. He's interested, which is rare when they're usually just looking for fun. Fred's got an eye on the two of you, Aria.]

Brilliant. Just don't set the house on fire.
