Sunset Shimmer and Sci-Twi arrived to the pier. Sunset helped Pinkie with the documents and paperwork, handing them over to the police. Sci-Twi stayed behind, further solving the case and convincing the policewomen to let them free. Something along the lines of "What would be easier to report: arriving to the station with a paper reporting a case of mistaken identity and a terrible confusion or… arriving to the police station with 6 WET cosplayers and still reporting a case of mistaken identity and a terrible confusion…?" Twilight kept talking and making sense (or boring the cops to death).

Meanwhile, Sunset returned to the edge of the pier and greeted Pinkie. She sat down on the edge, at a good 3 feet away from her pink-skinned friend, letting her legs hang freely. She took a deep breath of the warm ocean air and looked at Pinkie. Sunset tried to put on her "mean face" but couldn't. The situation was complicated, Rainbow Dash was on the loose, nowhere to be found, and yet… Pinkie had this ability of defusing people's rants and anger, most of the time.
Sunset asked: "Care to explain, Pinkie, exactly what happened?"

/a full recap later/

"Aaand that's how we got here" Pinkie concluded, she grabbed her tail, pulled it up and hugged it, making a rocking motion. Sunset felt that she should have been angrier, shout at Pinkie because of her antics even, but the situation entertained her.

There was not a monster on the loose, or a storm that menaced ships or a reality-bending being about to destroy a significant portion of life. In fact, this "sitch" felt fairly mild, at least by comparison to what they have faced through the years. Still, there was a lot of work to be done, if they were to stop the contagion of the mermaidifying curse.

Sunset was lost in her train of thought, when she snapped back into reality, as she noticed that Pinkie Pie was smiling, staring at her in a funny way, specifically at her legs.

"Ah, ah, ah, Pinkie. Social distance, remember" Sunset said
"Awww, but your tail would be so beautiful! I wonder if it would be orange or red!" answered Pinkie, giggling a bit.
"Pinkie promise, that you will not touch anypon… anybody again while we figure this all out."
"Aaaalright… I Pinkie promise."

Applejack, a few meters away, rolled her eyes and then found herself smiling.
