Well, Spain is pretty weird! (Even though he just wants you to buy Volume 3!) I think he's pretty in-character. I wouldn't put talking to himself or writing horrendous metaphors past him. Besides, it's an AU, and it's possible that their background would have changed the way they see things, even ever so slightly.

Your writing is lovely, and I'm really looking forward to the next parts <3 And I kind of want to see more of Monaco and France because they're adorable.
