Is it just me, or is it a production error that River asks the Doctor in the library if they've done the Byzantium yet? Asking the 10th Doctor if they've done something that she did with the 11th Doctor. Also, isn't that how we assume that the Doctor who was at the Picnic at Asgard was the tenth? We're introduced to River on the last day of her life, so when we see her, we're seeing a character who's entire life story has been written. Which means that from a writing point of view there are bound to be errors. That's the nature of writing things back to front. The only in-universe explanation I can possibly think of is that while River knows his faces she doesn't know what order they come in, which seems wrong somehow to me.
