Those traits are also had by Spitfire, so she isn't necessarily ruled out.

That said, I'll have to read it to know to more.

it had been Rainbow Dash who had come to Twilight's aid, passionately commending her bravery for taking on such a dangerous mission, and saying that any one of them would have done the same if it meant protecting the mares of Ponyville.

After a few more moments and a few more playful gropes, the two reached the cloud, then dove straight on into it. Twilight felt the touch of cool mist upon her face as they plunged into that fluffy mass, a feeling that would probably have been soothing, had she been in the correct mental state to appreciate it.

Good, she's not dumb enough to bring her back home.

I just couldn't help myself. I knew I had to do that again!"

It's very on brand for Rainbow to not think this through as much as she probably should.

On a serious note, this has been a delightful read. I can foresee 1 likely ending; This is an elaborate kinky game and the entire town is in on it. After the Prowler is somehow dealt with, another one takes her place. Possibly using ropes and Earth Pony strength.
