So let's say that the nobles of Hoshido and Nohr, as well as Azura and the Corrins, are doing something (they are in different kingdoms for this) and they get a video feed. They have never seem a video feed, and before they can say anything, it plays.

What would be shocking? Seeing Marth, Roy, Chrom, Lucina, or Ike in the video feed?

Also, would it be shocking to see them singing Lost in Thoughts (Nohr version) in the video before holding stuff that piques the interest of the nobles? Or should they just hold the stuff and talk, and then sing when the nobles go out to meet the video person?

This is just a random thought. 

It's not like I'm putting it into a story with dragons and princes, right? That would be weird.
