A/N: Written for anonymous-idfk on Tumblr. Sorry for the late update! I'm working on a few WIPs and work got busy but I'm adjusted so it should be faster in the future! Let me know what you think!

Both his appearance and voice were specifically designed to facilitate his integration into human society as the perfect partner.

So it shouldn't have come as a surprise that the kid could fucking sing. Because of course CyberLife would decide to give Connor a set of pipes while neglecting to give him a set of self-preservation. Of course the ability to sing took priority over protecting his own life, especially whenever Hank's was involved.

Fuck him though, it came as quite the surprise to Lieutenant Anderson that Connor could sing a gentle tune while holding a child. And judging from the not-so-subtle looks the officers in the precinct were giving him? Everyone else agreed.

Chris had come in on his day off, juggling six-month old Damien and a cardboard box in his arms when Connor offered to give him a hand. Hank was fairly confident the android had meant to grab the box, but much to the RK800's surprise, the child was hastily given to him with a muttered thanks before rushing to the archive room. Hank was going have to ask Nines later to hack the office's security cameras so he could get a picture of Connor's shocked face.

"Officer Miller, I'm not sure I'm properly equipped for child care," Connor had called after the retreating father.

"You two are the same age, just find some common ground, Con," Chris replied with a smile before disappearing down the hallway.

Connor made his way back to his desk chair, LED blinking yellow twice before settling on a calm blue. To the untrained eye, the kid's face was mechanical, devoid of emotion or empathy. To Hank and a select few, Connor was an obvious bundle of nerves. From the slight twitch of his left eye to the subtle bounce of his right leg, the android was anxious. He had no doubt in his mind that Connor would be flicking his coin back and forth if it wasn't for the bundle in his arms. "What's with the danger-yellow there, kid? Don't tell me you just looked up proper baby holding 101?"

His LED flickered yellow once again before switching back to blue, his eyes blinking rapidly as he read information that Hank couldn't see. Damien cooed as he was adjusted in Connor's arms, reaching toward the glowing light on the android's temple.

Hank was willing to bet that Conor had just fucking done that.

At the baby's babbling, Connor's face softened and he reached a finger out to Damien's reaching hand which the child grabbed with delight evident on his face. "He's so…."

"I think the word you're looking for is small, Connor," Hank had finished for him.

"Very much so, Lieutenant."

"Move your left arm up a bit so you're supporting his head a bit more, Connor. Is what Chris said true about you two being the same age?" Officer Tina Chen sat on the edge of Connor's desk, waving to Damien as she did so.

Hank's smile grew at the comment, nearly laughing at the slight frown that crossed Connor's face. With Connor's deviancy came a measure of pride, and Hank knew that Tina's question would bring out some smartass answer only Connor could come up with.

"Actually, Officer Chen, I'm two weeks and three days older."

Tina huffed along with Hank, eyes crinkling in amusement before she raised her arms in a surrendering gesture, "My bad, Con, my bad."

Connor gently pried his finger away from the chubby hand and reached around Officer Chen for his terminal, skin retracted. Before he could reach, however, Damien's face scrunched and Hank groaned, already knowing what was coming. At the child's sudden cry, Connor startled and his LED blipped crimson before settling on yellow.

Well god-fucking-damn it, Hank didn't know anything could make the most advanced prototype ever created jump out of his artificial skin, let alone a crying baby. "How do I fix this, Hank?"

If Connor was forgoing Hank's title while at work, the horror of it all, the kid must have been pretty fucking panicked. "Every baby's fucking different, Connor. Try singing?"

Both Tina and Connor hushed Hank as soon as the curse left his mouth and Hank rolled his eyes. "Studies have suggested that human children can understand words as soon as six months, Lieutenant."

"Don't use swear words around kids, Hank," he rolled his eyes harder while Tina continued speaking to Connor in a low voice, "Although it's not a bad idea. My little sisters used to refuse to go to sleep without a song when they were little."

Damien had continued squirming in Connor's arms, and his LED had stubbornly refused to switch back to the calm azure it normally was. But his face had finally switched from the panicked expression to a gentle smile as he returned his finger to Damien's hand, and he opened his mouth to shock the entire department.

"Hush now, mo stóirín, close your eyes and sleep. Waltzing the waves, diving in the deep. Stars are shining bright, the wind is on the rise, whispering words of long lost lullabies."

His voice was soft and had taken on a quality Hank had never heard from the android before. The low volume of his voice notwithstanding, most officers milling around stopped working to listen, not attempting to be discreet while moving toward the duo for a better listen. The grizzled police lieutenant himself didn't bother to hide his shock either and he knew if Connor was paying attention to him, he would have made some sarcastic comment about flies and his gaping mouth. Connor, however, didn't have eyes for anyone but the brown-eyed child hiccuping in his arms with tears streaming down his face.

"Oh won't you come with me, where the moon is made of gold and in the morning sun, we'll be sailing. Oh won't you come with me, where the ocean meets the sky and as the clouds roll by, we'll sing the song of the sea."

"Holy shit, Hank, dude's got a pair of pipes," Tina whispered to the staring Lieutenant.

Hank only muttered something about language under his breath, watching and listening as Connor's voice gently rose and fell with the lyrics to a song he vaguely recognized.

"I had a dream last night and heard the sweetest sound. I saw a great white light and dancers in the round. Castles in the sand, cradles in the trees. Don't cry, I'll see you by and by."

By this point, Chris had returned to the main floor, eyebrows raising at the scene before him. Nearly every officer in the precinct was by Hank and Connor's desks, listening with rapt attention. Slowly, Damien's cries began to quiet as the android detective continued singing in a gentle baritone and began to settle in Connor's arms.

"Oh won't you come with me where the moon is made of gold. And in the morning sun, we'll be sailing. Oh won't you come with me where the ocean meets the sky. And as the clouds roll by, we'll sing the song of the sea. Rolling, rolling, rolling, rolling."

Still nearly incredulous at the sight before him, Hank couldn't stop the muted smile from forming, blue eyes crinkling at the edges. Damien hiccupped once, twice before staring into Connor's eyes, his mouth slightly agape and cheeks red from crying.

"Oh won't you come with me, where the moon is made of gold. And in the morning sun, we'll be sailing free. Oh won't you come with me, where the ocean meets the sky. And as the clouds roll by, we'll sing the song of the sea. Grá go deo," Connor finished as Chris waded through the crowd, giving a few officers friendly shoves before clasping a hand on the android's shoulders.

"Thanks, Connor. I really appreciate it."

"It was my pleasure, Officer Miller," Connor's smile turns from gentle to forced when he takes in the crowd.

"Please, call me Chris. We're friends, and I'm technically off after all," Chris gives another officer a shove, "Get back to work before the Captain gets on all of you, show's over."

As the crowd disperses, a few sending Connor thumbs up and mimicked applause as they go, Connor returns Damien to his father. "It was my pleasure, Chris. It was an interesting experience, to say the least."

"Kids in general are an interesting experience, Con," Hank laughs, nodding at Chris as he leaves, "Didn't know you could fucking sing like that."

Connor gives him a rare shit-eating grin before returning to a more neutral expression, despite the light in his eyes, "CyberLife androids are designed to work harmoniously with humans. Both my appearance, and voice, were specifically designed to facilitate my integration," his voice is carefully dispassionate as he chooses his next words, "I suppose CyberLife didn't 'fuck up' with my design after all."

"Watch it kid, else you might overclock your sass module."

"Technically speaking, Lieutenant, it would be called my sarcasm program as a module is actually a combin-"

"You're walking home if you finish that sentence."

Connor's LED skips a merry blue as he connects to his terminal, "There's a 76% I'd still beat you home with the way you drive, Hank."

This fucking plastic punk was going to be the death of him.
