Ron was more than just a little frustrated after his conversation, if it could actually be called a conversation and not just talking at his daughter, and so he went off in search of his wife. Because if he had been frustrated with the talk he'd had with Rose, he could only imagine how his wife had felt.
He knocked once before he opened the door without waiting for a response and stepped into the office, to find Hugo with his arms wrapped around his mother. "Hey you two." He grinned seeing the both of them, and he ruffled his son's hair as he closed the door behind him. "Why don't you make yourself scarce for a bit, I need to have a talk with your mother." He grinned, thankful that Hugo just nodded and left the room.
"How are you?" He asked Hermione, brushing her cheek with the back of his hand for a moment, before he wrapped his arms around her just the way Hugo had a moment before.
