"How's the bank manager doing?" Batman asked as Oliver, Ralph, Barry and Lyla accompanied the banker to the hospital and then they met with the Dark Knight in an alley.

"He'll make it." Lyla said. "Thanks." She turned to the caped crusader.

"Wait, you know Batman?" Barry widened his eyes.

"We've worked together few times." Lyla admitted.

"I thought he was an urban legend created by the cops." Oliver said.

"What are the Green Arrow, Flash and the Elongated Man doing in my city?" Batman asked.

"Trying to figure out why Mercy Graves thought that this compass was worth dying for." Lyla showed him the compass they had taken from Mercy's deposit box.

Batman picked it up. "It's not working."

"Yeah, we know. But a speedster meta was willing to kill for it…" Ralph picked the compass and suddenly the needle started to spin like crazy. "What the—"

"How did you do that?" Oliver demanded in surprise.

"I don't know." Ralph admitted as Batman picked the compass but the needle stopped moving, even when Batman was shaking it and he tried to tap it.

"I tried that already." Lyla said before Batman handed the compass to Barry before is started to spin again. "Apparently, this compass works only for you." She pointed out.

"And any other metahuman. And you're saying that a speedster was willing to kill to get this compass?" Batman inquired.

"He's already killed Mercy Graves, who had a key to the deposit box, in which this compass was and you saw what he did to the bank manager." Oliver explained. "Who knows how many bodies has he dropped, just to get it."

"He must have been following us to get his hands on it." Lyla realized. "Caitlin surprised him and he ran away, when we confronted her in Mercy's apartment. He knew we would lead him to it."

"The question is, what kind of compass is it, that it works only on metas that someone is willing to kill for it?" Oliver asked.

"Excellent question." Batman said.

"Are you going to help us?" Oliver asked.

"A metahuman almost killed an innocent man in my city. I'd like to know why and make sure he doesn't hurt anyone else." Batman said.

Oliver, Barry and Ralph nodded in agreement before the latter spoke up. "How did you even know who we—"

"I've been keeping an eye on any potential dangerous metahuman from Central City, ever since 33.1 was shut down. I suspected that Miss Snow had survived." Batman said.

"She's not dangerous, she's just… lost." Barry explained.

"We need to figure out, who exactly this speedster is and what he wants, if it's the same one that killed Mercy and attacked Caitlin." Lyla said.

"I may be able to help. But I'd appreciate if you left my city right now and left that compass with me." Batman insisted.

Oliver, Barry and Ralph looked annoyed. "Look, man, we want to take this guy down as much as you do and…"

"He went after you and that compass and was willing to kill an innocent man to do it." Batman said. "I could stop him but I can't afford to let you get in the way."

"Who does he remind me of?" Barry drawled and Oliver rolled his eyes in annoyance.

"The forensics from A.R.G.U.S. are still combing Mercy's apartment. Maybe we'll find other leads than this compass." Lyla pointed out.

"If I find out what this compass is exactly, I will reach out, Miss Michaels." Batman promised. "But for now, just leave my city before things get uglier than they are."

"Come on, man…" Ralph grumbled before Lyla dragged him and Barry aside.

"Look, Batman could prove to be a valuable asset. I know how he works. Alone, he's very efficient but he has helped me and A.R.G.U.S. before. Trust me, arguing with him is a no-win situation." Lyla insisted.

Barry and Ralph turned to each other before sighing as they gave in before turning around.

"OK, fine, have it your way, Bat—" Barry trailed off as Batman had managed to disappear.

"Whoa. How did he do that?" Ralph stared. "A teleporter?"

"No. He's as human as I or Oliver are." Lyla said.

Oliver looked jealous and annoyed as Barry chuckled. "Still think that Batman is a—"

"Don't even start with it, Barry, or I swear to God…" Oliver growled and Barry snickered at Oliver's jealousy.

S.T.A.R. Labs

Caitlin was examining a blood sample in the microscope as Harry and Joe approached her. "Is everything alright, Snow?" Harry asked.

Caitlin sighed. "Honestly… I don't know."

"I'm glad you're back, Caitlin. I really am." Joe said. "I just hope… if there's something I can help you with…" Caitlin was hesitant before taking a breath and Joe noticed the guilty look in her eyes. "It's alright. What matters is that you're back… and we'll help you figure this out. It's no different than from when Killer Frost took over and you were helping Savitar…"

"It is different." Caitlin snapped before sighing deeply. "I don't know exactly what Felicity told you but… it wasn't Killer Frost, who killed those people." She raised her hand as it started to liquify. "It was all me. I chose to drown them. I chose to freeze them to death. All because I wanted to make them pay for what they did to me. But…"

"Caitlin…" Harry trailed off, not sure what to say.

Joe held Caitlin's shoulders. "When I look at you… I still see the kind doctor, who was helping Barry, when he spent nine months in a coma after the explosion of the particle accelerator. The same woman, who was helping him and Wally and with their speed. The same woman, who was side by side with us, when things were at seams. And nothing is going to change that."

"I killed six people." Caitlin snapped.

"You were alone and angry and afraid of coming back. What I'm telling you, is that you don't have to be alone anymore, Caitlin." Joe said. "We're still your family. And nothing is going to change that. We're always gonna be here for you if you need us."

"You're my best friend." Cisco said as he held her shoulder from behind, to her surprise.

"You guys are never gonna believe what happened." Barry said as he and Ralph and Lyla entered.

"Whoa, Batman is real?" Cisco demanded as Oliver, Barry, Ralph and Lyla filled them in.

"As real as the League of Assassins, apparently." Barry quipped.

"What kind of compass only works on metas?" Cisco asked.

"Good question." Lyla nodded.

Elsewhere

"The Bat has taken the compass." Johnny told Manchester as he entered his tent.

"Oh, bollocks." Manchester groaned. "Please, tell me you didn't kill anyone."

Johnny shook his head but Manchester snapped his fingers and clenched his fist as Johnny's leg cracked as he fell down. "Manchester—"

"You put a bank manager into a hospital and Barry Allen almost caught you." Manchester growled. "How many times have I told you that we don't kill humans, unless they try to kill us first? Do you want to create another Lex Luthor? How many of our brothers and sisters have been slaughtered already? How many more are going to be slaughtered because of your recklessness, you bloody fool? We're supposed to show that they don't have to fear us and you're doing exactly the bloody opposite?!"

"Alright, alright, I get it!" Johnny groaned as Manchester let go.

"Final warning. No dead innocents, or I will make you a permanent cripple and you can say your running days 'Cheers'." Manchester said and Johnny nodded in fear and understanding before limping out from the tent.

Shawna teleported into his tent. "Was that necessary?"

"Because of idiots like him, we just might face another genocide." Manchester said. "We're supposed to offer sanctuary and help for our kind and he's making us lambs brought to a slaughter, with bullseyes on our backs."

"If it hadn't been for you, they would have continued to hunt me." Shawna said. "I don't know how can I ever repay you."

Manchester looked at the clock. "I think that it's time for your performance, Miss Baez."

Shawna teleported before appearing on some kind of a stage in a tent. "Good afternoon, ladies and gentlemen. Welcome to one-of-a-kind performance that you never see anywhere else. Now, let's play a game called 'Peek-a-boo'. First five, who finds me, are going to win a reward."

Shawna teleported on one of the empty benches before one of the spectators turned around. "Peek-a-boo, I see you!"

Shawna teleported herself on a trapeze above as the people looked before one of them found her. "Look! Up there! Peek-a-boo, I see you!"

"Thank you, thank you." Shawna said as she handed the girl a giant elephant toy. "You have a good eye, young lady."

S.T.A.R. Labs

Caitlin entered the lab and sighed deeply. "It hasn't changed much."

"You OK?" Oliver asked as he and Barry entered.

"It's strange." Caitlin admitted as she looked around. "I thought that nothing would feel the same but when I come here… it's like I left just yesterday." She looked down at her hands and clenched her fists.

"I've been where you're at. We'll help you get through this, Caitlin." Oliver assured her.

Caitlin turned to Oliver with guilty eyes. "How can you even look at me, after knowing what I did? How many people I killed?"

"Because I've been where you're at right now. And what I know, is that there are two kinds of killers. The ones, who kill for the sake of killing. And the ones, that are in pain and are looking for a way to channel it. Those one, they are not beyond redemption." Oliver said. "What hasn't changed, is that we're friends. Just let us help you. I know how you must feel. That what you've been through has scraped your soul so much that you don't even recognize yourself anymore. And what you need right now, are good friends, who can help you pull back from that edge."

"How do you know that I'm not beyond redemption? That there's no helping me? What if I am past saving?" Caitlin snapped.

"If that were true, why would you even bother coming back?" Barry challenged and Caitlin didn't answer. All she did, was standing in the room, full of uncertainty, guilt and shame as Barry and Oliver were consoling her as Barry held her hands.

"She just needs time to settle in." Harry said.

"Yeah, maybe." Cisco nodded before suddenly, his nose started to bleed as a few moments later, he passed out, falling down.

"Ramon?" Harry turned to Cisco, who was lying on the floor, unconscious and blood was dripping from his nose. "Ramon?!" He turned to the microphone. "Barry, get to the cortex, now!"
