Jack's apartment was technically a one-bedroom, but only if you had no imagination and even fewer standards. The bedroom itself was more like an alcove with a curtain that swayed dramatically every time someone so much as coughed. The carpet was old enough to vote, the kitchen sink wheezed like it had asthma, and the fridge made a sound that Jack described as "deeply unsettling, but mostly non-lethal."

Still, it was his. Which meant it had space for two coffee mugs, four chairs that didn't match, and exactly one blue-haired ex-Cybertronian who had taken it upon herself to experience "human living" in the most intense way possible.

Arcee stood barefoot in front of the toaster, arms crossed, glaring at it like it owed her money.

"This machine is defective," she said, flatly.

Jack, juggling a half-warm mug of gas station coffee and the world's slowest call with the water company, leaned around the corner. "It's not defective. You just turned the dial too high."

"It's blackened. That's not toast, Jack. That's biochar."

He took a sip. "It's character-building."

"It's carcinogenic."

The toaster popped, launching a burnt slice into the air like a dramatic finale. Arcee caught it instinctively, barely looking, and studied the charred surface with the expression of someone genuinely offended by breakfast.

"I used to dismantle Decepticon mines with precision tools," she said, deadpan. "Now I'm losing to a bread heater."

Jack gave her a thumbs-up and went back to waiting for "Carol" from customer service, who had placed him on his fourth hold of the morning.

Arcee didn't hate her new form. She'd gotten used to the breathing, the blinking, the absurd number of muscles required just to hold a fork. But there were definitely downsides. Human skin was fragile. Human sleep was inefficient. Human clothes came in sizes, which, for someone used to being made of shapeshifting alloy, was baffling and infuriating.

Still—she liked waking up in Jack's bed. She liked being able to walk barefoot through the apartment, even if she still wasn't convinced about socks. She liked his weird, quiet routines: the way he made coffee with surgical focus, the way he always checked the door was locked twice, the way he talked to himself when he thought she was asleep.

Most of all, she liked belonging here.

Even if it came with questionable toast and deeply cursed plumbing.

That evening, Arcee stood at the window in Jack's hoodie and bike shorts, watching the neighborhood unravel into evening chaos. Somewhere nearby, a dog barked once and never again. Down the block, someone's car alarm howled into the void with operatic despair.

Jack was on the floor with an IKEA bookshelf and the desperate determination of someone who had lost control hours ago but refused to admit it.

She turned toward him, arms folded. "I still don't get it."

"Get what?" he asked, already knowing.

"This whole... apartment thing. Humans live in these tiny little boxes, stacked on top of each other like you're afraid of touching dirt. The walls are paper. I can hear your neighbor's TV. And she only watches shows about baking and yelling."

Jack tightened a bolt. "You're talking about Karen. Yeah, she's got... a niche."

"Why does anyone choose to live like this?"

He looked up, sweat clinging to his brow. "Because it's what we have. And for most of us, it's enough."

She considered that. "Still feels like a downgrade."

"So was falling in love with an Autobot who used to be a motorcycle."

She blinked.

Then smiled.

The next morning, they met their nemesis.

Mrs. Crandle.

Sixty-three. Florals. Clipboard. A walking, passive-aggressive warning label. She had the eyes of someone who'd personally rewritten the HOA bylaws to ban fun, and the smile of a python that just finished brunch.

"I just wanted to welcome your... companion to the building," she said, standing at their doorway with the posture of someone who'd been preparing this ambush all morning.

Arcee stared at her. "I'm here on a diplomatic exchange program."

Mrs. Crandle blinked.

Jack stepped in. "She's visiting for a few weeks. Cultural immersion. Very educational."

"Oh, how nice." Mrs. Crandle's smile went tighter. "Well, we do pride ourselves on quiet, orderly living here. No parties. No loud music. No... pets."

Arcee raised a brow. "What if I'm the one who bites?"

Mrs. Crandle made a small, squeaky sound and fled.

Arcee turned to Jack. "Do all humans respond to threats that poorly?"

Jack stared at her. "Did you just threaten to bite my neighbor?"

"She started it."

By midweek, Arcee had developed several strong opinions:

1. Showers were both soothing and dangerous. The hot water felt incredible—until she accidentally turned the knob too far and emerged with the scalded rage of a warlord.

2. Laundry was a minefield. She flooded the shared laundry room and nearly disassembled the washing machine after misreading "delicate cycle" as a challenge.

3. Cooking was a scam. Why did everything involve so many steps? And why did everything call for flour?

4. Sleep was inefficient. She missed stasis naps. But she liked waking up beside Jack. Even if he hogged the blanket.

5. Humans were fragile. She stubbed her toe once and seriously considered calling Ratchet.

And speaking of Ratchet—he'd stopped answering her calls after she left him a five-minute voicemail asking if heating pads counted as "field-grade pain suppression."

On Thursday, Bulkhead arrived.

He knocked once. Just once. The kind of knock that shook the frame, the walls, and possibly the fabric of reality.

Jack opened the door. And there, standing tall in all his glory, was a man in a leopard-print button-up shirt, cargo shorts, and what could only be described as "thrift-store aviators worn with terrifying confidence."

"Jackaboy!" he boomed, spreading his arms wide. "Your favorite Autobot has arrived in mortal flesh!"

Jack squinted. "...Bulkhead?"

"In the gloriously simulated flesh." Bulkhead did a slow spin. "What do you think? Rugged? Approachable? Slightly mysterious, with a hint of 'he owns his own boat'?"

"You look like someone's uncle who never recovered from the '80s," Arcee said, arms crossed.

Bulkhead grinned. "Mission accomplished."

He strolled into the apartment like it was his timeshare, flopped onto the couch, and promptly broke one of the legs. Without missing a beat, he propped it up with a stack of Jack's unopened mail.

"Let me guess," Jack said. "Miko talked you into this."

Bulkhead took off his shades dramatically. "Miko said I had 'incredible wingman potential.' Apparently I radiate non-threatening masculine energy. Like a golden retriever who knows how to mix drinks."

Arcee narrowed her eyes. "So you're... becoming human just to go to punk shows and help Miko flirt with women?"

"Exactly." Bulkhead leaned forward, eyes deadly serious. "This is cultural immersion, Arcee. I'm not just doing this for her. I'm doing this for the legacy of the Autobots."

Jack blinked. "You're trying to pick up women... for the cause?"

"Exactly," Bulkhead said again. "You get it."

Arcee rubbed her temples. "We survived Megatron for this?"

Bulkhead stood, brushed invisible dust off his ridiculous shirt, and turned to Jack. "By the way, your couch sucks. I'll bring a beanbag next time."

"You're not staying here."

"Not tonight," he said, winking. "Miko's dragging me to something called a 'rave.' I'm not sure what that is, but she said to wear mesh."

Arcee groaned.

Jack sat back down on the floor beside the bookshelf. "You know what? Fine. The world is weird. I give up. Let the Autobots go native."

Bulkhead nodded sagely. "Welcome to Earth, baby."

Arcee dropped down beside him, her shoulder brushing his. "He's going to get arrested."

Jack smiled. "Probably."

And yet... he didn't mind.

He didn't mind the chaos. The noise. The strange new normal. If anything, he liked it.

He liked her.

Even if the toaster still tried to kill them every morning.
