1. Brainy thought he was done with Kryptonians, after Clark left the Legion fifteen years ago.

He never believed he'd see a living person with the House of El coat of arms on their chest again.

Yet…there she was.

Kara thought she was done with Brainiacs, after she helped take down Indigo three years ago.

She never believed she'd see an organic being with that symbol on their forehead.

Yet…there he was.

"Brainiac-5. My friends call me Brainy."

"Supergirl. Nice to meet you."

2. "Clark never told you about us?" Brainy asked, slightly disappointed.

Kara shrugged. "I didn't see him often enough to ask about his previous adventures." she said. "I was too busy living my own, normal, boring life, and he was out saving the world."

She didn't want to sound resentful, but was afraid that she was coming off that way, so she changed the subject.

"Turns out, that was for my own benefit. He wanted to keep me safe, from the escaped alien prisoners who had vendettas against my family, and from government organizations like CADMUS that wanted to dissect me, among other things. By the time I did decide to start protecting my city as Supergirl, I was able to protect myself as well."

"That's Clark for you." Brainy said. "Protecting people was always his first priority, no matter the circumstances." He didn't protect me, though, when the time came. he added silently. But he didn't want to think about those events right then.

3. "The night before Clark was about to leave Smallville to start his reporting career in Metropolis, myself and a few of my teammates travelled back in time to recruit him to join us in the 31st century." Brainy said. "We're the reason he grew up to become the hero everyone knows him as in your time."

"So, what does this have to do with me?" Kara asked. "Why not go get him again, for whatever it is that was so serious you came here?"

Kara swore she saw Brainy blush dark green as he spoke. "As much as I would like to, his timeline needs to be left alone. If I did bring him back with me, it would be disrupted too much and possibly damage the space-time continuum."

"Is that all?"

"Also, I kind of wiped part of his memories."

"And are you going to do that to me?"

Brainy didn't answer. Instead, he said, "The Legion, the team I'm a member of, is facing another major crisis. We need your help, Supergirl."

4. "So, I will be able to see my family and friends again, right?" Kara asked.

"We're not keeping you forever." Brainy confirmed. "In fact, I can return you to the moment you left, no matter how much time we spend in the future."

"Good." Kara said, smiling. She pulled out her cell phone and started to make a call.

"Alex? You'll never believe this…"

"What is it? Your friend from the alternate universe showed up again? Lena asked you out on a date?" her sister asked.

"No, neither of those things…someone arrived in my apartment today. He says he's from the 31st century. He knew Clark, and apparently his team needs me. In the future. Apparently I'll be back in a few minutes."

"Another completely normal day for Supergirl, huh?" Alex remarked. "Stay safe, alright? I'll see you whenever you get back. Love you."

"Love you too."

The call ended, and Kara put the phone on the counter.

A few moments later, Kara had changed out of her work clothes into her superhero outfit.

"Alright, I'm ready." she told Brainy. In response, he activated the time bubble, and the two stepped inside, then disappeared.

5. "Guess we know why Brainy requested to go on this mission alone." Lightning Lad said, as Brainy and Kara arrived in Legion headquarters.

"Shut up, Garth!" said Phantom Girl, elbowing him in the stomach. She shot him a glare, which he responded to by rolling his eyes. She walked away from him, and went to go greet Kara.

"We're all very happy you could join us, Supergirl." she said, smiling at Kara. "It's been so long since we've had a Kryptonian on the team, and we're honored to have you here."

"She means we're desperate."

"Enough!"

Kara laughed. "Thanks for inviting me here." she said. "I'm honored to be a part of the team that made my cousin the hero he is."

Even if one of you is a Brainiac, she thought.

She'd have to ask Brainy about that later. But for now…

"So, guys." she asked. "What're we up against?"
