They have a few things to figure out.

"...okay... How are we going to explain... Well, this," he said, gesturing helplessly to Ruby once he had recovered. "To everyone?" He then gazed at her tail. "...and also, without your, um, lady parts, how exactly are we to... You know?" He rubbed the back of his head awkwardly

Ruby grinned cheekily. "Well, Master, with your permission, I can reform my legs. Only for whatever duration you specify though, then they automatically return to being the tail. I can also change my clothes back," she explained.

"What's the point of the tail anyway?" Jaune asked. "It seems kind of... Inconvenient."

"That's part of the point, Master~!" Ruby chimed, pulling her tail up in front of her, bending it roughly where the knees were and wrapping her arms around it, like a floating fetal position. "It's a symbol of a genie's bondage! See, while I have it, I'm firmly attached to the lamp, and thus, can't get far from it! And it's like a chastity belt! Basically, a leash and that rolled into one as a part of my body!" As she spoke, she ran her hands over the ethereal appendage tenderly, clearly loving her tail and what it represented.

Jaune blinked. Okay, he could actually see the appeal of that. When put that way, it was hot. "But wait, the lamp isn't exactly bolted down or anything. What's stopping you from just carrying it with you as you float about? Doesn't make it much of a leash..."

Ruby giggled, and decided to show, rather than tell. She floated back to the lamp, grabbed it, and pulled. "Hhhnnnngh!!!" she grunted, completely failing to budge it.

"...okay, what?" Jaune asked, walking up and picking the lamp up without issue. "...can you not move your own lamp or something?"

"Ding ding ding!" Ruby responded playfully. "I'd have better luck trying to push Remnant out of its orbit! It's quite hot, actually, being so thoroughly bound!"

"...I'll take your word for it, I'm not a submissive," Jaune replied. "Okay, so, um... Form your legs whenever it is convenient from now on. And by convenient, I mean when you actually need to be away from the lamp, or out in public view. Um... And change your clothes back. Don't call me Master in public, and... You think you can act like your former self?"

"Easily, Master! After all, I'm still my former self, just now as a side to me instead of my entirety! So it's not really acting!" Ruby assured him as she reformed her legs, then snapped her fingers, the harem outfit vanishing, leaving her naked for a brief moment, before her old outfit reformed entirely on her body. "...so... How do we play this?" she asked him.

"Um... I guess... We just act like everything's normal for now, but exchange scroll numbers, and find a time to meet up to figure more things out?"

"Can do!" she nodded, whipping out her scroll, Jaune setting the lamp down to do the same, before they headed out, the door thankfully no longer sealed shut. Ruby then stopped, and grinned at Jaune. "...forgetting something, Master?" she asked.

He blinked, before he panicked. "The lamp!" he exclaimed, before running back into the room to get it, Ruby laughing at her Master's ditziness.

"Guess Master's a bit of a himbo," she remarked to herself.
