Loki still had not made progress toward using the facilities independently. He was clearly quite capable of vanishing things, but would not or could not vanish his own messes.
"I'm on to you," Tony pointed at Loki, though he steadfastly refused to have anything to do with helping with said messes. "You like making other people handle your crap. Literally."
Thor had made a point to deposit Loki's waste into the toilet, to try to solidify the idea that that was where waste was supposed to go. "The mortals call it a porcelain throne, brother. Fit for a prince."
"Though even I don't have a toilet made of gold," Tony mentioned, offhand. "I could, of course, if it'd get you to actually use it."
Tony did, in fact, have a gold toilet delivered.
Loki, to make their lives difficult, began flushing anything but that down the toilet. He tipped Tony's expensive scotches into the porcelain bowl, watched them swirl down the drain, though he didn't do so with Natasha's vodka.
Like with his buckets and cauldrons, Loki managed to cram several things that simply should not have been able to fit down the pipe, such as several car parts and tools from Tony's workshop. The toilet was about to swallow Steve's shield, of all things, before it was rescued by its owner.
Loki simply laughed through Steve's lecture about respecting personal property, but Steve wasn't laughing. Nor was Thor, though his disappointed-older-brother look seemed to only encourage Loki.
"You need a taste of your own medicine," Tony declared. He began casually swiping Loki's books and trinkets. Loki wordlessly yelled with outrage and took this as a declaration of all-out war. He began filching tools from Tony's workshop during his increased visits to do just that.
"You are truly lucky to have me, to locate your missing items," Jarvis remarked in the middle of their week-long pilfering contest. In all honesty, it seemed rather tamer than when he'd amused himself by redecorating London's famous landmarks.
At last, a truce was called. Or, rather, Loki simply grew tired of the porcelain throne, likely thinking of new ways to wreak havoc on the tower's inhabitants.
"Brother, my beloved Jane will be visiting!" Thor beamed like the sun, but Loki clearly didn't share the enthusiasm. He glanced at Thor and turned back to his book.
Taking care of Loki took much of Thor's time, and Jane was busy with her research. They had not seen each other for some time, and even when Thor tried to call, he was often distracted by Loki. He suspected that his brother purposely caused mischief just to interrupt his calls.
Thor did not worry that Jane would be prejudiced; she'd been kind to him when he was newly banished to Earth, and she'd heard his tales of Loki's antics.
When Jane and Darcy arrived at the tower, Loki paid them little notice, but Jane's clothing suddenly transformed to look much like Loki's wizard costume, a robe with stars. The stars rearranged themselves into different constellations and shapes, and Thor wondered why Loki did not use this power to show them what he wanted.
Darcy teased Jane about her much gaudier outfit, but Thor smiled at Loki. Surely he'd picked stars for a reason. "Indeed, my beloved Jane studies the skies and stars."
"You must be Loki," Jane spoke directly to Loki, which only made Thor love her more. "Thor told me of how you once turned into a snake."
Darcy grinned. "I bet you've seen Thor do loads of embarrassing things. Too bad you can't tell us. There's got to be a way. Do you like painting?"
Darcy loved hearing the Avengers share Loki's recent misadventures, and Loki chortled when Darcy told of shocking Thor with her taser.
Thor was not entirely sure what a michelin star was, but he doubted it was one of the many covering Jane's evening dress. When he'd seen them dressed to go out, Loki had changed Jane's clothes again and refused to change them back.
Tony had sent them off with strict orders not to throw glasses on the ground, as if Thor hadn't learned that years ago. Besides, that was really the pot calling the kettle black, since Tony had done far more scandalous things in formal settings.
Thor loved listening to Jane talk of her research, seeing her eyes light up like the stars she studied, but he couldn't help worrying what sort of trouble Loki was causing back at the tower. Elaborated by Darcy, of course, who seemed even more inclined to encourage Loki's mischief than Tony was.
He had a suspicion Darcy's taser might be involved.
"You know, I'd be fine with some, as Darcy says, Netflix and Chill." Jane remarked.
"We would not be alone," Thor warned. For a tower so big, with each member of the team having a private floor, it was surprisingly difficult to get privacy, especially when one most wanted it. And Thor wasn't referring to JARVIS with that.
"I'm sure we could find somewhere," Jane smiled.
They left the restaurant, and Thor scooped Jane up bridal style before summoning Mjolnir. He'd left it on the balcony to ensure it didn't smash through Tony's walls.
He flew them back to the tower, which was still standing. Thor might have given Loki a bit too much credit, or not given his teammates enough.
Thor and Jane relaxed on a couch, sharing a tub of ice cream. Loki waited expectantly until Thor held a spoonful out to his brother.
Loki loved ice cream, but at least he refrained from reaching into the tub with his hands. Darcy cajoled Loki away with a larger tub of ice cream from the freezer. Loki was quite smug about having the tub to himself, and having more than Thor and Jane combined.
Of course, the rest of their date was… interesting. Tony thought it was funny to instruct Jarvis to only allow the televisions to play NOVA space documentaries, and strolled by to casually engage Jane in scientific debate whenever things might be getting intimate.
Thor frowned. He would have thought that, with Tony's reputation, he wouldn't have interrupted others' attempts at intercourse. Jane eventually threw a pillow in Tony's face as Darcy dragged him from the room with vaguely threatening remarks about her taser.
"I have a heart condition!" Tony protested. "You can't restrict me from my own tower! This is a communal floor!"
"Like you haven't made out on every floor," Clint said from the air vent.
"Barton!" Thor called, and Clint quickly crawled back through the vents to leave them in peace.
