Prince Blueblood has one heck of a family reputation to live up to.
Even Twilight Sparkle is considered better royalty than him, and she's fresh out of her coronation. Blueblood gets no respect, and he tries his best to ignore this by losing himself from time to time in the embrace of hard cider.
As it turns out, he's not the only one with problems.
This surprises Blueblood greatly.
