"This wasn't quite what I had in mind when you invited me to spend the weekend." said Twilight. She and Celestia were seated in the Royal Gardens enjoying a relaxing afternoon tea. "I was expecting tea given how much you like it but I wasn't expecting...."
A loud bang went off jostling the fine porcelain slightly, both alicorns however remained composed and seated.
"You mean the explosions?" said Celestia in a slightly weary voice. "It was meant to be a calm and relaxing weekend for the two of us especially since we've both been busy lately." Celestia moved herself so that she would be seated next to the lavender alicorn rather than across from her, she wrapped her marefriend with a wing, "Yes the plan was for a nice weekend to unwind until well this."
As if to emphasis her vague proclamation of "this" another loud bang rang out.
Twilight shook her head and sighed, "How did all of this start?"
Celestia gave her own sigh, "This morning I was rudely awaken by Luna barging into my quarters. She yammered on for a while about Discord being a thief and something about a sock or something being lost or stolen. I can't remember the details well, I was far too groggy this morning to think through the fog in my mind. Anyway Discord claimed innocence until Luna found him with her missing whatever and now here we are."
A even louder bang shook the table, the tea service, and the annoyed and tired alicorns.
"So what is Luna doing?" Twilight asked wanting to make sense of things.
At this moment a pair of stallions walked into the Gardens with a mysterious, covered cart, the elder of the two had a spotless white coat and a black beret while the younger had a darker coat and a brown fedora.
"Your Majesties, have either of you seen where Princess Luna has gone to?" asked the white stallion.
Both were about to deny knowing Luna's whereabouts when Luna herself appeared before them.
"Ah, thank you good stallions. Now then what have you brought out?" Luna said as she used her magic to lift the mysterious contents out. "Ah, more of the useful red candles and some very explosive white putty. A few powders and chemicals...." revealing that the cart was full of explosives; TNT, C-4, napalm, gunpowder....
Leaving Luna to her explosives and her revenge plans, Twilight asked, "Again what exactly is she doing?"
Celestia began massaging her head to relieve the building headache, "An experiment, "Could an Immortal Dracoequus Withstand Several Pounds of Explosives Unharmed". Although I think Tons is a more apt term than Pounds at the moment."
An even louder bang rang out, its shockwave were stronger than before, it seemed that Luna had really let loose with the explosives.
Before them came a Royal Guard in full field gear who kneeled, "Your Majesties, I regret to inform you that the Solar Chariot has been destroyed."
Celestia froze, trembling she asked, "The Solar Chariot? The well wrought wooden chariot decorated in golden tones and accents? The exceptionally nice one that we just had replaced for how many bits?"
The Guard merely nodded, Celestia at this point gave up, she facehooved and collapsed into her marefriend's lap.
