Prince Blueblood is absolutely convinced that Tempest Shadow has lied to Princess Celestia and that she is still plotting to conquer Canterlot. Now it's up to him to stop her.
Unfortunately, he is (1) dead wrong, (2) not a fan of comic books, and (3) not trained in espionage, counter-intelligence, special operations or anything else that would be useful in such a situation. But he does know which flowers go well with her coat and what restaurant can offer the best candlelight dinner opportunities, so… that’s… a start…?
Prince Blueblood / Tempest Shadow, because I love my random and obscure shipping constellations and because these are two very different, very fascinating characters who can probably learn a lot from each other. (Also maybe some Capper/Celaeno on the sidelines later on?)
