Warren and Maggie
Warren didn't really want her keeping him either. He wanted to escape back to obscurity and isolation, glaring at the people at the party. That was where he felt most comfortable.
"Yeah," he said - the closest he could come to actually telling her he'd enjoyed meeting her. "See ya."
Whether he did or not, he didn't really care about at the moment. But that was Warren, and as far as social interactions with him went, this one hadn't been particularly bad.
