I blame my flatmate for this one. He did this to me two weeks ago, so I'm exacting my revenge on Hank and Connor.

The aftermath of the android uprising had left Detroit in a state of flux for many weeks, and even now things were not completely settled. Trouble was mostly minor, fortunately, as everyone navigated the new world order. One of the major problems, however, had been finding somewhere for the thousands of free androids to stay.

It turned out some higher profile figures in the city were public supporters of android independence, and Markus had been offered various locations to house the new population. It was a win-win situation: the androids had the chance to build their own homes, while the humans who extended the gesture got the publicity. Markus knew full well it was the motivation behind the amnesty extended, but some of the humans he had accepted offers from turned out to be genuinely invested in the future of the androids. That had made things much easier.

Once a week, Connor would make a trip out to visit Markus and the two would share various updates. Connor's position within the DPD in investigating android crimes meant that Markus was greatly interested in what the former deviant hunter uncovered, while Markus often gave Connor tip-offs to other crimes and provided useful information. Not only that, but the two had turned into great friends after things settled down. The two RK models had discovered they shared a lot in common.

Not least of which was a similar sense of mischief. That little discovery had been by pure accident after Markus asked why Connor had been grinning so much the day he had tampered with Gavin's coffee.

This week was slightly different, however. After being informed of a human protest group vandalising part of the apartment block Markus and the others were living in, Hank had joined Connor in checking things out. It wasn't the first time Hank had gone with him, the police lieutenant was familiar with most of the more prominent androids now, but it would be first time they were investigating a scene. He was glad to not be investigating homicides anymore, he'd seen more than enough death to last him a lifetime.

When the pair pulled up in Hank's car, they were slightly surprised to see Markus standing outside with North, Simon and Josh. All four androids were engaged in easy conversation and all gave a friendly greeting as Connor and Hank approached. Markus and Connor hugged warmly while Simon and Josh shook hands with Hank. As they said hello to Connor, Hank swung out and caught North's hand in mid-air. "Pinch my arm again and I swear to fuck I'll shoot you, North," he warned with a stare.

The female android just smirked and winked at him as he let her hand go, only for him to get a slap to the arm instead. He hissed and rubbed the spot as she shrugged. "You never said anything about slapping," she smirked before wandering over to ruffle Connor's hair. The detective glared as she snickered, and Hank couldn't help but laugh. Apparently North had worked out Connor's distaste to that particular trick.

Once everyone had finished saying hello, Markus smiled at the duo. "It's good to see both of you, I just wish it wasn't for investigative purposes," he spoke warmly.

Hank folded his arms after shrugging. "Humans being assholes? Tell me something new."

North raised an eyebrow at him. "Do you make it a habit of insulting yourself? Or are you just trying to take away my entertainment?"

"Didn't say anything untrue, I am an asshole; but depriving you of amusement is always a win in my book."

"Bite me, old man."

"You first, bitch." Simon and Josh just shook their heads as they led the way inside, Markus and Connor sharing a laugh as they saw Hank jump away from North with a shout. "I was fucking joking, North!"

The pair hung back slightly, Markus' eyes dancing in amusement as he watched the other four ahead. "He seems to be in a good mood, today."

Connor smiled broadly. "I think he's just happy that we've actually got two consecutive days off after today. He intends to, quote, 'do sweet fuck all'."

Markus roared in laughter. "It's hilarious whenever you swear, Connor, even if you're quoting Hank. You've got two days off, have you? In that case, I call this perfect timing." Connor looked at him oddly before Markus retrieved a small bottle from his pocket. The detective scanned it briefly and smirked as he realised what it was. "Let me know how it goes, yeah? Carl's the one who gave me the inspiration for this one."

That earned a quiet laugh from Connor as he swiftly pocketed the bottle with a smile. "You told Carl about Hank and I's prank war?"

"I mentioned it in passing, and it turns out this was a common one when he was younger. And I'm not going to lie, I enjoy hearing all your stories about it: so much so that relaying them to Carl gives us both enjoyment."

Connor snickered, the image of the older man laughing at their antics making him happy. "I hope you realise that I'm going to drop you right in this one if it goes wrong."

Markus just winked at him. "What was it you said to me once? 'Statistically speaking, there is always a chance for unlikely events to take place?' I'm making no promises, Connor." He placed an encouraging hand on Connor's back as they strode in. "Come on, you'd better check it all out before Hank and North legitimately hurt themselves. I swear they're worse than children."

When Connor and Hank returned home that night, the pair were in great moods. After weeks of pestering by Connor, Hank had actually started cooking more often, and tonight was one of the designated 'non-takeaway' night. As the older man got started on making food, Connor made sure he was adequately distracted before slipping into the bathroom. Hank noticed his brief absence, but when Connor returned with a new book from his bedroom, he didn't ask any questions.

An hour later saw the two of them relaxing on the sofa with Sumo between them. "Ugh, think I'm going to take a shower, get rid of all the stress from this week," Hank commented idly, huffing as he shoved Sumo's massive form enough to be able to stand. "Think you can manage to keep yourself out of trouble?" he teased lightly, earning a raised eyebrow from Connor.

The android kept a deadpan expression as he answered. "Don't I always, Hank?"

A bark of laughter was his answer. "Right, as fucking if." When Hank moved away, Connor's face changed to a knowing smirk as he refocused on his book. He was waiting for the inevitable reaction when Hank finished up.

He only had to wait ten minutes.

"Connor!" The android had to bite his lip at the furious roar from the bathroom and fought hard to school his face into an appropriate expression when he heard the door be wrenched open.

Only for it to be a completely wasted effort when he saw Hank. A chuckle escaped Connor before he could control it, and a second later he dissolved into side-splitting laughter. "This isn't fucking funny, Connor! Why the fuck is my hair blue?!"

Hank's anger abated slightly at seeing Connor is stitches, he'd never seen the android laugh like that before. It eased the embarrassment at finding his hair a shade of fluorescent blue following his shower, his beard a similar colour but more muted. It was about twenty seconds before Connor stopped laughing, but the android was still giggling at the human as he answered back. "Surprise?" he offered in answer. "Don't worry, Hank, it should wash out before we need to be back in the precinct on Monday. I wouldn't do anything to cause you embarrassment at work."

"Thank fucking Christ for that, I'd hate to have to find an explanation for this." His face morphed from annoyed to a challenging smirk. "You're a couple up on me now, you brat. I'm going to have to find a way to get back at you."

Connor winked at him. "Looking forward to it, Hank. Although I hope you realise I currently cannot take you seriously."

"Shut the fuck up."

Except things didn't quite work out like that. The universe was working against them this time, and the temporary blue dye didn't vanish by the time the pair returned to work. Hank just glared in Connor's direction when he was the butt of the jokes for the day due to his blue-tinged hair.

And, as promised, Connor informed Markus that he had swiftly offloaded fault in his direction when the prank went wrong. The detective knew he'd been had when Markus sent him a smug message back via their mental network.

You didn't think I'd pass up an opportunity to catch both of you, did you?

The war had a new participant, and Connor would be lying if he said he wasn't excited at the prospect.
