Back at home for the day, Kara was still having trouble coming to grips with what she'd witnessed at Ferris Air. Barry's powers had enormous, far-reaching implications, especially since he didn't seem inclined to believe that he needed to hide them and go on living a normal life the way Kara had been doing with her own powers since the day she had arrived on Earth. Mulling it over further, she realized that part of her problem was that she lacked a fundamental understanding of exactly what Barry's powers were. Knowing that the only place she was going to be able to gain that understanding was STAR Labs, Kara headed for there, via normal human transportation this time.
"A dimensional barrier ruptured, unleashing unknown energies into our world," Wells was saying as Kara approached the Cortex a short time later. "Antimatter, dark energy, x elements-"
"Those are all theoretical," Barry interjected.
"And how theoretical are you?" Wells countered. After a pause, he continued, "We mapped the dispersion throughout and around Central City. Though we have no way of knowing what or… who was affected, we've been searching for other metahumans like yourself."
"Metahumans?" Barry asked.
"That's what we're calling them," Caitlin explained.
"I saw one today," Barry said. "He's a bank robber, and he can control the weather."
"This just keeps getting cooler," Cisco interjected.
"This is not cool, alright?" Barry said in an urgent, panicked voice. "A man died. Mardon must have gotten his powers the same way I did- from the storm cloud. He's still out there! We have to stop him before he hurts anyone else!" At that, Kara heard footsteps heading for the door. Barry's, no doubt.
"Barry!" Wells called out, and the footsteps stopped. "This is a job for the police."
"I work for the police," Barry insisted.
"As a forensic assistant," Wells pointed out.
"You're responsible for this," Barry said. "For him."
"What's important is you!" Wells shouted. "Not me. I lost everything. I lost my company, I lost my reputation, I lost my freedom, and then you broke your arm, and it healed in three hours. Inside your body could be a map to a whole new world- genetic therapies, vaccines, treasures buried deep within your cells, and we cannot risk losing everything because you want to go out and play hero! You're not a hero. You're just a young man who was struck by lightning." After that, Barry came storming out of the Cortex, shoving past Kara without acknowledging her presence in the slightest. Kara waited a few minutes to give everyone Barry had left behind time to cool off before she entered the Cortex herself.
"How much of that did you hear?" Wells asked when he saw her come in.
"Enough," Kara replied simply. Taking a seat in one of the rolling office chairs scattered around the room, she said, "You're making a mistake."
"Barry is too valuable to risk," Wells insisted, shaking his head.
"Barry is a person," Kara said, anger slipping into her voice at the way Wells was talking about her brother like he was an object, a tool to be used as he saw fit, "not a piece of tech. He's a person who makes his own choices. Besides, you… you don't understand him. Not like I do."
"Well then, please," Wells said, a hint of sarcasm in his voice. "Enlighten us."
"Barry is stubborn," Kara replied. "If there's something that he thinks he should or needs to do, and you tell him that he can't do it, that just makes him want to do it even more. And if you won't help him, he'll find someone else who will. He'll get Joe to help him, or he'll, I don't know, run to Starling City and track down the Arrow." This last Kara offered as a ridiculous suggestion, the most extreme measure Barry could possibly take, but it occured her even as she said it that he might do exactly that. Oliver Queen was, after all, the person who had inspired Barry to use his new powers to help people, to be a hero, at least as far as Kara was able to discern from what Barry had told her about Oliver and what she had observed of Barry with his powers so far.
"He's going to do this," she went on. "With or without you."
"Then what do you suggest we do, if we apparently can't stop him?" Wells asked, an angry, bitter tone in his voice.
"Let me help," Kara replied. "Let me join him in his new found crusade."
"We all saw what she did at Ferris Air," Cisco spoke up, addressing Wells and Caitlin. "She's plenty fast enough to keep up with Barry."
"I'm more than just fast," Kara put in, intentionally cryptic, already fearing just how much of her powers she would have to reveal and the questions they would lead to. "And if Barry's so insistent on being a hero, I'm the best person to prevent him from getting himself hurt or killed." There was a long silence while the group, but especially Kara, waited for Wells' answer. They couldn't do any of this without his consent and his help.
"Alright," he conceded at last. "But you'd better hurry and go track him down. Wherever he went after he left here, I have a feeling that he's getting himself into trouble already."
