Ping. Ping Ping.

Hank glared at Connor, watching the android flick the coin up and down, up and down, each flick landing perfectly back on the palm of his hand. Connor was always so focused with that coin, always staring off into the distance as he fiddled around with it. It always raised questions with Hank and with a sip of his drink, he asked.

"Why do you always play with that coin Connor?"

Connor blinked from his trance, looking at Hank, his fidgeting not stopping. Now the android fiddled the coin on the fingers, the coin rolling from side to side on his knuckles.

"I'm not sure, Lieutenant. It calms me in a way." He answered.

"Calms you? Like, what is that…." Hank scratched his head, thinking of the word. "What those kids do… Ehm…"

"A stim?"

"Yeah, that."

Connor searched through his database for the proper definition of stim, he repeated it. "Self-stimulatory behavior, also known as stimming and self-stimulation, is the repetition of physical movements, sounds, or repetitive movement of objects."

Hank chuckled. "Well look at you go slick, got anything else in that brain of yours you wish to define?"

Connor thought about it. "Well, what do you want to know, Lieutenant?"

Hank merely shrugged and leaned back on the couch. "I don't know. I'm just wondering why you fiddle with that coin so much."

Connor didn't say anything, tossing his coin from side to side. Hank internally enjoyed watching Connor play with his coin, he's expressing himself, something that was most human of all. Every day, he noticed Connor was becoming more in touch with the world, becoming more human, which was a damn good thing in his eyes. Back then, he used to despise Connor being around, but now, he enjoyed his company.

Sometimes, he even reminded him of Cole.

Hank smiled a bit and glanced at his beer bottle, the bottle was half empty. Then, he glanced back at Connor, feeling full.

"Hey, Connor?"

Connor glanced up at him, now going back to balancing the coin on his knuckle.

"Where did you learn to flip your coin like that?"

"I'm not sure, Lieutenant. I just picked up on it, I guess. But… I can teach you?"

Hank raised an eyebrow. "You want to teach me how to flip a coin?"

Connor glanced down then, flipping the coin up one last time before holding it in his hand. "I'd like to."

Hank scratched his head, mulling it over. Is he going to let an android teach him something? Hell, maybe this would be useful for him someday. He hasn't been occupied with anything since Cole was alive.

"Ah, fuck it. Teach me." Hank sighed, putting his drink on the table.

Connor blinked, his eyebrows raising. He glanced down at his coin for a moment, taking in that Hank was willing to be taught and he went over to him, sitting next to him on the couch. Reaching into his coat, he grabbed another coin and gave it to Hank, in which Hank questioned if he has been collecting coins behind his back. Politely declining, Connor began to talk to him about how to flip a coin.

Shifting his finger under the coin, he flicked it upwards, the coin falling back into his hand. Allowing Hank to try, Hank launched the coin away from his hand, cursing under his breath as he went to go get it. After a few attempts and better explaining, Connor watched as Hank successfully landed his first coin flip, a smile tugging at his lips. Over and over again, he watched as Hank landed his flips and a feeling filled Connor's chest. This feeling spread from his head to his toes and now he was excited to teach him more.

He felt happiness. He felt pure joy rush through his veins.

"I noticed you tried to do my passing trick back at the tower," Connor said, his smile brighter than before. "Do you want me to teach you? I must warn you though, it's more complicated than just a simple flip."

Hank smirked at him. "You saw, huh? All right then, teach me!"

Connor's face blushed deeply and he chuckled. The rest of the night, Connor and Hank practiced coin tricks, tricks of various difficulties and techniques to achieve them.

Hank snores soundly on the couch, drink back in his hand, with Connor flipping his coin next to him, his bright smile still on his face.
