DM: Did you really bake a whole cake just to eat most of it yourself?
Pinkie Pie: Duh! That's the best part!
Applejack: Oh man, Ah haven't touched a string instrument since like fifth grade.
Twilight Sparkle: I'm surprised you're not dancing either.
DM: Nuh-uh. My house, my dignity. Not after the last time.
Twilight Sparkle: Yeah, I totally get that.
Shining Armor: Wow, the Wonderbolts sound kinda awesome when you put it like that.
Rainbow Dash: Right?! Royal mercenaries who mean *business!*
Fluttershy: So if Rarity caught the bouquet, who's she going to marry?
Rarity: Whoever would be the most interesting, I suppose.
Fluttershy: More interesting than her?
Rarity: Oh yes, it's a high bar.
Princess Cadance: You know, if you're craving some high-stakes drama... I'm putting together an online Vampire game soon.
DM: I might have to take you up on that– Wait, was that a pun?
The terms "royal" and "mercenary" do not go together... unless you're the monarch of Hesse, perhaps. I imagine Celestia "offering" the Wonderbolts to other nations to, ahem, *settle* a quarrel or else.
They actually go together fairly well. Back in the day, kings would traditionally keep a guard of mercenaries, because locally raised soldiers might have loyalties to their fellow countrymen that could entice them to the anti-king side of potential disputes. The Swiss Guard at the Vatican are the last remaining vestige of this.
