Charlie and George
At this George looked at his brother in a little wonderment. Penny and Genevieve? Oh this was going to be a fine mess his brother had gotten himself into though he wasn't going to say anything. He had other siblings who would do that for him. His big brother needed someone on his side- and Merlin knew that George owed him, at least that.
"Well done you," He finally let his well practice smile up on his face. He took a sip of butterbeer almost wishing for something a little stronger, but he had to keep his head on him, "and what do you mean kinda... sort of? either you're dating someone or you're not big brother."
