It was late that night in Canterlot, one of the city's bars still open. This had become fairly common place with Princess Luna's return and with her the Night Ponies, who being nocturnal required 24 hour businesses.
Seated at one table was a Changeling, clad in his kind's black chitin. While his kind fed on love, the tastes of some equine food was still pleasurable, not to mention being capable of eating normally necessary for disguise.
Shortly there after, an unicorn royal guard came and set down at the bar as well. After ordering a simple salt water, he looked over to the Changeling. "Hey there..."
The Changeling gave a polite nod in return. "Hello..."
"...So, I know the Bat Ponies like being out this late because they're nocturnal, what brings you out this late?"
The changeling knocked on his hard exoskeleton. "Ponies are still getting used to this. So sometimes it's nice to go out without too many stares...What about you?"
The Guard gave a chuckle. "Relaxing a bit...been a stressful time recently, what with the multiple attacks on Equestria...uh...no offense."
The Changeling didn't seem all that offended. "None taken. We did something wrong. The only ones who have a right not to be guilty over it are the ones who sided with you all. I wasn't one of them, so sorry."
"It's fine, we ponies forgive easy..." the guard replied, the two sitting there for a few more moments. "...So...if you wanted some peace in the day, couldn't you turn into something prettier now that you're good guys?" he asked, showing sincere respect and politeness.
The Changeling chuckled. "Some of us came up with the same idea and asked Queen Cadence about it," he replied, looking to him. "She said 'You're already beautiful, and you don't need to change your appearance to prove you're good for real. Your own actions prove whether you're good now or not.' I believe her honestly."
The guard nodded after giving it some thought. "Princess Cadence was always one to see the beauty in things. She'd be one to know."
"Besides, her husband pointed out it'd be kinda shallow for ponies to think we're good just cause we look good, you know?" asked the Changeling.
"True to that...toast?" he asked, holding his drink in his telekinesis. "To Princess Cadence and Prince Shining Armor being right?"
"Well to me they're Queen Cadence and King Shining Armor, but sure. Toast," the Changeling replied, the two clanking glasses and drinking.
"Name's Robber Fly by the way."
"Daywatch, nice to meet you."
