[Nothing weird has happened in the store so far, thankfully, and Dorian himself is grateful for that. He needed a bit of... normalcy if you can call this that. Sure it's all the stuff he doesn't know about but he loves learning. And so long it stays this way, there won't be any problems (or further increase of paranoia).

When he hears Robbie speak up, Dorian looks up from the book he's holding and enthusiastically waves.]

Oh! Robbie! It's a book on musical instruments. I didn't know there was a lute that runs on electricity! As well as fiddle!

[A guitar... maybe he did hear of it, from Eddie, but forgot for a moment.]
