"So.. if I were to tell someone after you two have had your talk.. would that be fine?"

It's very hard to gauge Inigo's intentions as he's saying that. He's not looking particularly cheeky, for one, and Inigo is usually pretty genuine about his emotions. Especially in non-serious situations like this one. Maybe he's asking because he's got someone in mind he wants to tell it to?

(Will Elidibus' nightmares become reality?!)

Or maybe Inigo is just really curious. Who knows why he's asking!
