Princess Twilight Sparkle thought it would be a good idea to pair up Prince Blueblood and Tempest Shadow to work together. He is a clever and talented diplomat and negotiator with a “charming” personality; she is an experienced warrior who explored - and conquered - lands beyond Equestria. Surely they could help promote diplomatic relations between Equestria and its neighbors.
 
That is, if the two of them could stop getting on each other’s nerves!
