(Clark's first meeting with Brainiac 1)

"I knew you." Clark said, looking with admiration at the being who'd offered him the universe. "We were friends."

"I do not recall this." Said Brainiac 1. His monotone barely concealed his dislike of the Kryptonian's idealism, and Clark wondered how long it had taken for this Brainiac to become the one he'd been used to. "Though we can be a team, if you accept my offer."

"Let me think about it, and I'll get back to you." Clark sounded discouraged, but as he flew off, back to Metropolis, he was only thinking one thing- I want to trust him.

(Alternate universe of Pesky's Heart of Steel fic, where Brainy was impersonated instead of Clark)

"You don't love me." Clark decided.

"You're fairly clever, Superman." The person who wore Brainy's face said. "I admit I expected far less from you."

"So who are you, really?" Clark asked. "What have you done with Brainy?"

The impostor smirked, shifting into a female Coluan. "I am Fabala Dox, the mother of your precious Querl Dox."

"You're Brainiac 4."

"Yes."

"Brainy told me you abandoned him at birth."

"Abandoned…that would be the appropriate word." She said. "But that's not really fair, coming from the man who left behind an entire century for one person. Rather selfish, don't you think?"

(Aftermath of a meeting between Clark and Brainiac 4)

"What did they do to you?"

"She." Clark corrected.

"Alright, what did she do to you? Who was she?" Brainy asked, assessing Clark's physical condition since their run-in with the Dark Circle. They hadn't left a mark on him, of course, but he was still shaken from the encounter.

"Of all people, you should know who she is. Calls herself Fabala Dox."

"Mother. Of course." Brainy says. "It makes sense now. But you still haven't answered my other question."

"Well, she threatened me, mostly. Made me nervous. Talked about you. A typical mother-in-law stereotype, really."

"You'll have to explain that."

(Set after 2x08, Clark gets amnesia)

"Who are you?" the Kryptonian asks, mind a blank slate.

Oh no. Brainy panics. The memory-wipe worked too well.

Then he reconsiders, turning away from Clark while wearing a smirk his ancestor would be proud of.

He'll get his memories back eventually. Might as well use this to your advantage while you can.

He turns back to face the other boy, smirk disappearing.

"Oh, I'm so glad you're okay!" Brainy says, beaming at him. He embraces him, and Clark accepts the hug, surprised but still confused.

Brainy remains smiling as he holds Clark's face in both hands.

"I'm your boyfriend."

(Continuation of the 'amnesia' prompt)

"This was never right."

Brainy's back was turned, and though Clark hadn't known him long after he'd lost his memories, he still knew this wasn't like him.

"How?" Clark asked, putting a hand on his shoulder.

He turned around, eyes glowing purple.

"I was not supposed to treat you like this." He said. "I did not want to feel…anything… for you. That is all him."

Clark removed his hand, startled.

"What do you mean?"

"I am truly sorry, Kal-El." He withdrew the crown of Kryptonite from himself. His eyes were their normal color. "But he and I made a deal."

(Kara introduces her friends to her friend from an alternate universe)

They're in Kara's apartment when the speedster appears.

"Barry! Welcome back!" she says, hugging him.

"Kara! Hi!" Barry says. The other two watch them, confused as she was when Barry first appeared on her Earth. "Who're your friends?"

"Right, you haven't met them yet!" she answers. "This is my cousin Clark, AKA Superman, and his boyfriend Querl, AKA Brainiac 5."

"Nice to meet you both, I'm Barry Allen." He says, shaking their hands.

"And they're both from…?" He points upward. Kara nods.

"Earth-1 could always use more heroes, especially now."

"Why…?"

"Come on, I'll tell you when we get there."

(Prompt: "It's in my blood- I just can't help it.")

"It's in my blood - I just can't help it. That's what you think, right? Because I am a Brainiac, I can't possibly want to do good in the world?"

"I didn't say that." Kara said. "I might've thought it at first, but…"

"You didn't have to." Brainy's expression grew colder. "It was written all over your face."

"Let me finish. I was going to say I know you're different now. I have a very close friend who also has a family name people don't trust. But she fights it, she's just as strong as you. And I respect that."

(Brainy/Clark, "I'm not wearing that")

"I'm not wearing that." Clark said, looking at what Brainy presented to him. Apparently, he'd found it in the New Metropolis mall, and "could not pass it up".

And he'd bought it full-price. Clark didn't know what that said regarding his priorities spending-wise.

"Not even for me?"

Clark blushed bright red. "You mean…No! You won't see it, anyway."

"True, but I will know it is there."

"Besides, wouldn't it be a bit tacky for me to wear Superman underwear?"

"What, would you rather I wear them instead?"

"If that's what you want, go for it. I won't see them either."

(Clark/Brainy, "Is that my shirt?")

"Is that my shirt?"

"Um. Well."

Clark grabbed the blanket off his bed, covering up his chest.

"Too late, I already saw it. It was, right?"

Clark's nervous smile and pained-looking nod confirmed it, and he lowered the blanket to reveal the purple-and-black shirt Brainy usually wore, except the sleeves were now almost non-existent, and it resembled what a 21st century human would call a 'crop top' on Clark's taller frame.

"Hey, in my defense, you wear my shirts all the time!" Clark protested, as Brainy took in what he was seeing.

"I never told you to take it off."

(Clark/Brainy, Disney movies)

"What do you mean, you've never seen a Disney movie?"

"Clark, you know I didn't have a traditional childhood." Brainy says. "I don't know what you speak of."

Clark knows about Brainy's upbringing, spent many nights upset for Brainy's sake over it, how he could never really be a child.

"That changes tonight. My room, eight o'clock, no distractions." Clark says.

Brainy smiles. To the surprise of nobody, Clark's still cute when he's demanding. He agrees, as if there was any way he could refuse.

When Clark wakes up the next morning, Brainy's still enraptured by the movie currently playing.
