So he really didn't remember the proposal.

John raked a hand back through his hair with a deep sigh, shaking his head in denial.
"Are you okay John?" Alex asked gently, no real signs of worry evident in his features. John met Alex's eyes and he nodded thoroughly, surging forward and throwing his arms around Alex. Alex didn't hug back.

"I'm just glad you're okay, finally," He smiled into the embrace, noticing how Alex still stood stiff against the table. He pulled away awkwardly, straightening out his collar professionally and clearing his throat. "D-Do you want to try walking?"

"Why'd you bring me back?" Alex asked curiously, dissing John's question completely. John's eyes widened and he frowned at Alex, shoving his shaking hands in his pockets.
"Because I love you, Alex, you weren't ready to go," he muttered.
No, I wasn't ready to let go.
Alex continued to stare at him lifelessly, his eyes glowing gently as he pressed his lips into a thin line. "Why do you ask?" John questioned nervously. Did he not love him anymore?
"Just, curious," Alex replied nonchalantly, scanning his eyes over John's face and memorising that expression. Pain, doubt, sorrow. He'd have to get used to seeing that expression.

So if this was the book I was gonna write there was going to be a heap of character developmenty stuff as John figures out that because Alex is a robot, he is incapable of feeling the same emotions he felt pre-ressurection. As a result, he no longer loves John. John is frequently frustrated with Alex as everything he does is monotonous and bland, but he slowly picks up on the emotions John displays towards him, learning them until one day Alex blows a fuse. (Robot puns)

John walked into the lab, a stack of files balanced in his arms and tired purple bags hanging under his eyes. He smiled when he saw Alex sitting at John's desk typing, but frowned when Alex met his gaze with the same steely cold eyes he was used to seeing.
Suddenly, Alex sighed and gave John a small smile, the same smile John saw when Alex first woke up, and his heart swelled.

"Hey that's new," John laughed weakly, dropping the files on the table. Alex's smile dropped and he looked at John in confusion.
"What's new?" he asked quickly, the metallic undertones in his voice ever so prominent.
"The smile, I like it," John smiled, sorting the files onto the shelf.
"Smile?" Alex questioned, cocking a brow at John. John stopped what he was doing and turned to stare at Alex.
"Yes Alex. The smile, you just gave me." He uttered slowly, worry laced through his voice.

"I don't smile John. You should know, you built me," he muttered bitterly, turning back to the computer with a glare. That's new too.
"What are you implying?" John asked, crossing his arms and leaning back on the shelf, biting his lip to hide his smirk.
"I don't feel emotion, John," He snapped. "I'm a robot."

John hid his mouth behind his knuckles, the smile uncontrollable now.
"What the fuck are you smiling at? You think this is funny?" Alex growled, standing up from his seat and pressing his hands on the desk, leaning over the computer to squint at John accusingly. "You don't think I want to feel emotion? Because I do, ho ho I do. Did you think about how I would have to suffer when you were building me? No. You only thought about yourself. Because you're a self centered prick John!" He yelled, his voice loosing the robotic undertones for a moment. His eyes burned bright blue, framed by furrowed brows. John coughed up a small laugh, now clutching both hands to his mouth. "Stop laughing! You asshole! Is how I feel a joke to you?" He hissed, slamming his hands on the desk.

John stared at him with wide eyes, his smile brighter than the sun as Alex glared at him, his body shaking with anger and fists clenched on the desk.
"Say that again Alex." John ushered softly. "The part about how you feel," John grinned suggestively.

Suddenly everything clicked into place. Alex's pupils dilated with a gentle whir and he stepped away from the desk.
"I feel. I feel. I feel angry. I feel, frustrated, and mad." He began to speak in amazement, lifting his hands and inspecting them carefully, as if he was somehow magically human again. The glowing blue veins and metal bones under his skin were still there, but he didn't feel empty like he usually did. He wanted to flip a table. He wanted to punch John and tell him to fuck off. "G-get out," Alex ordered, looking down at the desk with wide eyes.

"No Alex-" John protested but Alex raised his arm, the palm of his hand opening into a light canon aimed right at John.
"I said get out," He growled as the weapon hissed to life, a blue glow bright in his hand. John squinted at Alex.
"You can't hurt me Alex, I programed you that way, you can't fire that thing at me," John spoke quietly, shaking his head.

"Guess there's a flaw in my code," Alex growled, shooting the canon just past John's head. John didn't flinch, raising his eyebrows at Alex expectantly.

"There evidently is, I programmed that thing not to fire within a 5 meter radius of myself," John grinned, knowing Alex purposely missed his head, before frowning. He needed to be gentle. Alex hadn't felt raw emotion for 2 months now, this was probably an extremely overwhelming experience. "If you're smart enough to overrun your programing, you're smart enough to know shooting me won't solve things, so how about we sit down and talk?" John offered, taking a slow step towards Alex with his hands raised defensively.

Alex charged up the canon again as John came closer but powered it down as John reached a hand out and held his, closing his hand into a gentle fist and disarming the weapon.
"Why are you angry?" He asked carefully, rubbing his thumb over Alex's knuckles soothingly. His hands were cold, like the metal under his skin. If John focused really hard he could feel the gentle hum of electricity pulsing through Alex's body.

"I didn't ask to be brought back to life," Alex spoke quietly, the anger disappearing from his face. Pain, doubt, sorrow. Alex could feel it on his features. He had seen it on John's face enough times, and he was seeing it again now.

"I'm sorry Alex," John spoke quietly, dropping his gaze to the floor. "I thought I was doing the right thing, I thought you would come back, and you would still love me, a-and we could-" John explained carefully, being interrupted by Alex, who's eyes now were purely illuminated electric blue.

"Live happily ever after? I thought of all people you would know John, life isn't some perfect fairytale!" He lectured sternly, his voice gradually rising to a furious yell. "I died. And you decided you could play god, and bring me back, but here's the catch John, the flaw in your perfect creation? I-" this was going to sting.
Good.
"I don't love you!"

Time froze and John's breath hitched in his throat. Deep deep down, he knew it all along, but hearing those words leave Alex's lips, that shattered him. He stood frozen on the spot until time resumed, tears welling in his eyes and blurring his vision. Alex glared at him ruthlessly, but it soon softened as he watched John slowly break down in front of him, the light in his eyes dulling until it was gone completely. He took a step forward but John quickly stumbled back, hitting the shelf, his breathing heavy.

"You don't remember," John croaked, hastily wiping his tears away. "You proposed to me," he whispered, keeping his eyes downcast to the floor. "Right before you died you proposed to me! And y-you said you would- would always love me," he sobbed, falling against the shelf and sliding to the floor. "And n-never leave me," he squeaked, hiding his eyes behind his hands. "And just like that, you were g-gone,"

Alex felt guilt pool in his stomach and he bit his lip nervously.
"If you can learn to yell, and hate, and fill yourself with fury, why can't you learn to love again, huh? Just hold me, and tell me everything will be okay, even though I know it won't!" He cried, digging his nails into his palms and throwing his head back against the shelf. "I know it won't," he repeated in a weak mumble, streams of tears spilling down his cheeks.

Seeing John so distraught on the floor made Alex feel something new, the anger bubbling inside him slowly melted away, replaced with what he could only assume must be sympathy. He didn't know what to do. He stared at John crying, wracking his brain for an appropriate response.
What would the old Alex do?

Alex hummed in thought before slowly walking to John's side. He slid down the shelf and sat beside him. He sat for a moment, staring at John falling apart beside him, before he slowly lifted his arm and awkwardly raised it over John's shoulders. He lowered his arm and as soon as he touched John, he surged forward and wrapped his arms around Alex, crying into his chest.

Alex jumped in shock and stared down at John with wide eyes, frozen for a moment, before gradually pulling John closer, rubbing his back with his icy cold hands.
"Everything will be okay." Alex whispered cautiously, leaning back against the shelf slowly.

John looked up at him briefly with doubtful, tear-brimmed eyes, his hands shaking and twitching as they clutched Alex's shirt desperately.
"They'll never be as pretty as you," Alex spoke softly, followed by a gentle whir as he closed his eyes.

Then he felt a soft pair of lips meet his, and he felt love.
