He stares at her because even though she's clearly drunk and loose-lipped, he didn't expect her to say that. Especially not so loud, in the streets, where people could hear her. He is also concerned by how much she's had to drink and the fact that she's walking home alone. He sighs to himself, shaking his head, thinking he didn't know how he'd ended up here, but he can't just leave her here.

"Fun. Yeah. You're drunk," he tells her again. He has dealt with plenty of inebriated bar goers to know that whatever he says to her, she probably won't remember that well in the morning anyway. "I've called a cab. I'll get them to take you home."
