Oliver untangled himself from the railing he had been holding on to and picked Sara up as soon as Ava released the catch on her harness. He ran her to the MedBay, the rest of us following close behind.

"Gideon, what happened?" Ava asked the AI after her girlfriend had been placed in one of the beds.

Gideon scanned her body, then announced, "It appears that Mallus could only exist on Earth-1, and even though he has already been defeated, there were some residual effects that the of the strain of possessing her left on her body. The sudden disconnection was what harmed her. I've given her a minor sedative and some painkillers, she ought to be fine once they wear off in a few hours."

"Thank you, Gideon," Ava sighed in relief.

"In the meantime, there is something I need to show you, if everyone would please make their way back to the bridge."

Through all the commotion, none of us had noticed a sharp jerk in the hull of the ship, or rather, realized we had felt it until we felt another on our way back to the bridge.

"Guys, what was that?" Caitlin asked tentatively.

"I'm not sure," Nate answered. "Let's just get back to the bridge, I'm sure we'll figure it out."

Ava was the first to arrive, and promptly exclaimed; "What the hell!? Why is there a woman flying out there?"

The rest of us piled in and began to laugh as we realized who she was talking about.

Kara was floating just outside the front window, hands on her hips and a mildly annoyed expression on her face.

"That's Kara Danvers, or Supergirl, as she's known on this Earth." I answered.

"You wanna let me in?" She called.

"Go around to the Cargo Bay, we'll open it for you," I called back.

"I wasn't expecting you guys here for another day!" She exclaimed, hugging me.

"Well, I guess we're just efficient," Ray joked. "That, and, we probably put the wrong day in the time drive."

Kara looked at the group of people in front of her for a moment before asking; "Where's Sara?"

"About that…" I began hesitantly.

"She's in the MedBay," Ava answered for me.

"Sorry, who are you?" Kara asked her.

"Ava Sharpe, Director of the Time Bureau on Earth-1 and Sara's girlfriend," she explained, introducing herself.

"Kara Danvers, otherwise known as Supergirl," Kara smiled at her, and they shook hands.

"Anyways," Ava began. "There was a time demon on Earth-1 who possessed Sara's body for a while, and even though we defeated him, John Constantine- I absolutely hate the guy, but he can be useful sometimes- he did some sort of mystical scan on her body and was able to tell us that there were still some residual effects of the time they had spent bound together in her system. Unfortunately, Mallus could only exist on Earth-1, and leaving our Earth so suddenly must have caused the connection to be broken. Forcefully. She's in the MedBay right now, like I said, sleeping off the cocktail Gideon whipped up for her."

"Gideon had told us all to come back in here so she could tell us something when you showed up," Oliver told her.

"Thank you, Mr. Queen," Gideon said, her holographic head appearing above the center console. "You all have probably noticed the broken glass on the floor."

"Well, yeah, but why'd it break?" Zari asked.

It was shattered by the force of Captain Lance's scream when we crossed Earths. I had been wondering how this had happened, although my suspicions were confirmed when I compared the data from scanning her body a few minutes ago to the circumstantial evidence."

"What did you find?" Dinah asked, worry evident in her voice.

"I went back measured the volume of her cry, and it was far higher than the human voice should be able to give off. In fact, it was comparable to that of the Canary Cry used by the original Black Canary, Laurel Lance."

"That would explain why I heard you guys get here from all the way in Midvale," Kara muttered.

"Yes, it would," Ava said. "But what does this mean for Sara?"

"It means," Cisco piped up from the other side of the room, "That she's a Meta."

"She's a what now!?" Dinah exclaimed.

"A Metahuman," I said. They're people who were born human but got powers at some point in their lives. I became the Flash when I was struck by lightning the night the Particle Accelerator exploded in Central City a few years ago. Caitlin and Cisco's powers came from the same event, but they remained dormant until I accidentally time traveled the first time."

"The first time?" Ava asked me warily.

"The first time was a complete accident. I was running really fast in order to keep a tsunami from hitting Central City a few years ago. The second time was more on purpose. I went back in time to the night my mom died and saved her life, then lived in that timeline for about three months, until I started losing my memories of the original timeline. At that point, I went back and set time back on track, but there were repercussions I didn't expect. Long story short, one of them created Alchemy, a follower of Savitar, the god of speed. He was really just one of my time remnants from the future, but that's a whole other story. Alchemy gave Wally his speed."

"If you ever do that again, my team will hunt you down." She warned him.

"I have no doubt that you will, which is one of the reasons I don't mean to time travel unaided again," I told her. She nodded.

"As a change of topic," Kara said. "I'm going to go fly to Metropolis to pick up some extra help. When I get back, we'll all head to the DEO. Sound like a plan?"

"Absolutely," Oliver decided. "See you in… an hour?"

"Or less."

Kara flew off, and most of the rest of us stayed in the bridge to discuss the upcoming battle and what Sara's recent promotion to Metahuman meant for our chances.
