Seth was pleased to hear that Cho was taking her wand. Working for the DMLE, he knew she was as aware of the dangers as he was, but he couldn't help looking out for her. She was a sweetheart and he didn't want anything to happen to her.
He grinned when she said he didn't bore her. "It was the opposite in my family. My brother and I are pretty close, always have been, but my sister drove me mental when I was a kid. She was always so bossy, still is actually. It's only really since I left Hogwarts that we started to get along."
"You don't have to sound so surprised," he teased her as he picked up his wine and took a sip. "I'm more than just witty banter, I'll have you know."
He was enjoying himself too, which actually was a bit surprising. He hadn't even thought about his original intention for the evening, so taken was he by the conversation and learning more about her.
