[Claude has a please on the tip of his tongue that's about as sarcastic and irreverent as the prayer he once said to her in the goddess tower after the dance, but she's already asking him another question, so he'll hold that back for now.]

The surface similarities are evident, and I'd be a liar if I denied that. But everything Teach and I-- 'Teach' is the Byleth from my world-- went through... That's irreplaceable.

It's more like the Byleth I know had a twin brother, they grew up together, but at some point they split and went down different life paths. He's no more Teach to me than I would be the Claude from his world. But I still understood him in a way most people never will... And before I knew it, I began to cherish the time we've spent together here, too.
