"I…uh…" you stammer, swallowing nervously as Nightmare Moon's face stops searching to instead focus on you.
She leans in closer, inspecting your costume, "A noble attempt at replicating our likeness, but not the one we seek. Thou art smaller, as well."
"Well, you see, Princess, that's….that's…." you swallow again. This is rough.
You're about to start again when Apple Bloom puts a hoof over your mouth.
"He uh, disappeared, Princess," she says with over emphasized relief, "Just stopped out here and poof! He was gone! My friend and his….friend, showed up right after he disappeared. I think maybe it was a trick or somethin'.">>502037
You can't let her cover up for you, and you butt in to explain everything, though you don't say it was Harley who cast the illusion and do your best to keep her out of it. For now.
Eventually, Nightmare Moon/Princess Luna sighs, then sits on the ground in front of you and Apple Bloom.
"Tell us the truth, then. Did thou perform this stunt with malicious intent?"
"NO!" you yell, before blushing and toning it down a bit, "No! No no no, I just thought Apple Bloom was in trouble and….things got out of hand."
She nods, "Concern for ones friends is a good thing. Though you needn't have been truly concerned, we merely act in such a way for Nightmare Night. We would never harm our subjects…"
You can't help but notice Harley is conspicuously absent as Nightmare Moon/Princess Luna talks to you and Apple Bloom for some time about Nightmare Night and appropriate pranks and causing a panic like that.
"The next time you wish to impersonate us, you should warn us. And the town."
You bow your head and apologize, but eventually she has you raise your head and smiles in your direction.
"We do not hold it against thee, since thou didn't know the extent of what would happen. Besides, imitation is the highest form of flattery, or so our sister says."
With that she lets the two of you off the hook, and everyone returns to the crowd of ponies back at the statue and explains it was an elaborate joke gone a little wrong.
"So, in light of this, we decree Nightmare Night to be concluded, so that all may have a more pleasant evening and not fear any more surprises," Luna announces after changing back into her more regal form, "Though it must be said: These fillies did a marvelous job in scaring us all, they would be more careful about it in the future."
The town applauds the decision, before Luna adds:
"And compliment whoever replaced the statue I impersonated so quickly. We, or I, wouldn't have expected it to be back so quickly."
With that, the night is concluded, the crowd scatters, and you, Apple Bloom, and the statue, are soon all that remain in the clearing.
You turn to explain to Apple Bloom, but she just puts a hoof up, stopping you.
"Look, I trust y'all, and I'm darn beat from that much scarin' in one night. You can tell me at school sometime or somethin'. For now, I'm goin' home."
With that, she picks up the sheet that was her costume and throws it across her back, plodding home on her own.
You wonder where Harley got to before the statue itself giggles, nearly giving you a heart attack again as it changes to Harley herself, who hops down from the pedestal with a grin.
"What a night! I don't think I'll ever be able to top that kind of scare!"
>Scold Harley for her trick>Praise Harley for her trick>Let's just…go home. We'll deal with this later.
