It took me a little while longer to get this chapter started. It will be kind of a two part story, starting with Earth-4 Lily Stein's origins.

If you haven't read Welcome to Earth-1 before this, there's a section where E4 Lisa tells E1 Lisa how she and her brother were taken in by the Steins after their parents died. The beginning of this is kind of a flashback to it.

"You have to learn all this?" Lily Stein whined as she paged through the textbook her older brother was using in one of his college classes.

Leonard pretended to look offended. "You don't find it interesting?"

"Nah," the ten year old shook her head. "It's boring."

"Yeah," Lisa added from where she was sitting against Leonard's bed. She had already gone through the book. "Sorry, Lenny. Mick's textbooks are cooler."

Their brother's best friend smiled smugly from where he sat.

"Forget break," Leonard groaned. "Mick, let's go back."

"Not my fault you want to major in criminology," Mick laughed as Lisa stood up to peer through his chemistry textbook.

"Well, not every one of us is a genius who plans to double major," Leonard shot back, barely holding back a grin. "Nerd."

Mick shrugged. "Your sisters like this nerd better."

"Yeah, he has cooler classes," Lisa chimed in as she sat down beside Lily so they could look through Mick's textbook.

The girls' brother sighed. "You two are terrible sisters."

"No way!" Lily shook her head.

Lisa crossed her arms and looked over at Leonard. "We're the best. We're angels."

"About that," Leonard pushed himself off his bed. "I heard that you two got into a fight a few days ago with some kids at school."

The sisters turned towards each other. They had put the incident behind them, or so they had thought. The bruise on Lisa's cheek had nearly healed, and the scratches Steven had left on Lily were mostly gone save for one band aid. When Leonard had come home for fall break, they had hoped he wouldn't notice or find out. Everyone involved had all gotten off with a warning, and Lily and Lisa had been sat down by their parents for a talk about fighting in school.

Mick stood up and murmured something about going to get something from downstairs. Lily could see that he wanted to give them a little space, although she wished he'd stay.

"What happened exactly?" Leonard asked once the door shut behind Mick, staring at the two of them. "Neither of you usually gets into fights."

Lisa swallowed. "Some kids were picking on me."

"How come?"

"They found out I was adopted," Lisa said in a quieter voice. "They wouldn't leave me alone when I told them too. Then Lily told them to go away, but they didn't listen. One of them pushed me, so Lily jumped on one of them. Then we both started fighting them."

Lily nodded to confirm the story. Lisa had kept out some of the details about what the other kids said to her, but it hadn't been very nice anyways. She didn't regret tackling Steven after he shoved Lisa. Even if she'd gotten a warning about fighting, she would do it again if people tried to bully Lisa.

Leonard turned to Lily. "So you jumped a kid?"

"He said that Lisa wasn't really my sister 'cause Mom and Dad adopted you two," Lily told him, revealing only one of the things Lisa had had to hear. "He wouldn't stop it. Who even cares that you're adopted? She's my sister and you're my brother."

Her brother inhaled sharply after she said this. He looked down for a few minutes before lifting his head back up. Leonard was smiling, but his eyes looked a little watery. Reaching forward, he ruffled Lily's hair. Lily grinned a little, glad to see that he didn't look mad at what she had done.

"You're a good sister," he told her.

"What about me?" Lisa chimed in.

Leonard laughed and nodded. "You're a good sister too, Lisa. You're both good sisters."

As Central City started to come more into view, Lily's phone began to vibrate in her pocket. Placing her bookmark in her book, she pulled out the device to see Leonard's name pop up on the screen. She accepted the call, holding the phone up to her ear while the train sped into the outer edges of Central City. "Hey."

"Hey," her brother's voice replied. "I meant to call earlier, but something came up with a case. Are you back from Star City yet?"

"My train's pulling in now," Lily glanced around her, noticing for the first time how crowded the train had become. "It's packed. Everyone wants to see the particle accelerator start up."

"It goes online pretty soon," Leonard reminded her. "Mick's been waiting for this moment for so long. He can't wait to see what comes from it. Offered me the opportunity to be there with him when he turns it on, but work came up."

"Shame," Lily lamented, settling back in her seat. "I'm happy for him."

"Did things go okay in Star City?" he asked. "Did the university over there agree to help you?"

Lily sighed, looking at the case beside her. "The board said no. They're stretched thin on funds and won't take on any new projects, even though they said they were interested in FIRESTORM and its potential."

"You'll find something," her brother said as the train slowed to a halt at the station. "Maybe you can talk to Mick?"

"That'll be my last resort," Lily replied as she picked up the case holding the FIRESTORM matrix. "Hey, my train just pulled in. Talk later?"

"See you later, sis."

Lily ended the call and exited the train. Instead of heading home like she had planned, she ended up following the sea of people going towards STAR Labs. Most seemed to be on their way to see how things were working out, but there were some protesters mingled among them. Lily wove in and out of them, clutching the case holding what could be her greatest accomplishment close to her chest.

As she made her way up the steps to the plaza in front of the building, the ground shuddered. There was a muffled boom that shook STAR Labs next. People started shouting and pointing at the sky before turning to run. Lily looked up as people pushed past her to see a golden wave rushing up into the sky. It pulsed outwards in a wave as a fleeing bystander ran into her. FIRESTORM's case fell from her arms and tumbled down the steps.

The scientist pursued her project through the mess of people. They were all nearly far gone from her as she bent beside the case. It had come open in the fall, and the matrix was now lying next to it. Lifting it up to check for damage, Lily felt the hairs on the back of her neck prickle and whirled around to see the golden wave. It rushed towards her and slammed into her body like a strong wind. Agonizing pain set into her entire being, as if she was on fire, before Lily blacked out.

When she awoke in an alleyway, the body she was in was not her own.

Dun dun dun! In the next chapter, the story for Linda Park.
