As soon as Princess Celestia and Flash Sentry arrived at the Throne Room, Twilight Sparkle and Sunset Shimmer quickly made space for him, making Flash confused but sat between them anyway.
Princess Celestia gave them a stern look. "I know that both of you--- Twilight Sparkle and Sunset Shimmer --- are rivals and are my students."
The two mares looked at the ground.
".... And both of you like Flash Sentry." She continued.
Flash, Twilight, and Sunset Shimmer blushed redder than before.
"I do not mean to humiliate you by telling the whole Equestrian universe that the newly-crowned Princess and her fire-colored maned rival are fighting over one of the youngest and newest members of the Royal Guard. Flash, as one of the members of the Royal Guard, you should break the fight of Twilight Sparkle and Sunset Shimmer, but why you did not do it? I understand the fact that you, Twilight Sparkle, and Sunset Shimmer are the same age, and I am old enough to understand stallion's and mare's troubles."
Flash Sentry stood up, "But Princess! I didn't do it because I was afraid that it would only made it worse!"
Princess Celestia grew more sterner. "As one of the Royal Guard, it is your duty! You would break the fight if you even had enough courage! It does not matter if it would only made it worse."
Twilight, at last, having the chance to speak, stood up. "Princess Celestia!" She started, "I was the one who started it. I was jealous because Sunset Shimmer was Flash's first marefriend. I loved Flash so much that I did not wanted anypony to steal him away from me!"
Princess Celestia shook her head, doubtful. "Then why didn't you just talk it out?"
Twilight grew silent.
"Sunset Shimmer, do you have anything to say, hm?"
Sunset Shimmer shook her head.
"You see, you are all young to fight over some stallion that you both like. Try to work it out. Equestria has nothing to do with jealousy and etc. If Flash chooses the other mare, then it is alright. Now, if you do not mind me, I'll go to the Dining Hall to eat my chocolate cake."
Flash, Twilight Sparkle, and Sunset Shimmer burst out laughing.
