“Regina?”

There really should be an awkward pause here or a glare or something to show her anger at Gold looking for her sister when he should be looking for her instead. But there's not because what anger? There's no anger here. Why would there be any anger?

“Haven't seen her today, but if I do, I'll certainly tell her you're looking for her.”

And she will too. Because that would be the nice thing to do. It'd be absolutely horrible if she didn't let Regina know about this. Absolutely horrible.
