"There's not much we can do to stop Savage from returning," Oliver said. "He's immortal and can only be killed by Carter and Kendra. Or at least, that's what Mr. Hawk Man said. Not sure whether to trust him fully."

"Oh come on, Oliver," Cisco teased. 'It's not Mr. Hawk Man, it's just Hawkman. Leave the names to me."

"Speaking of which, we can just grab their Earth-2 doppelgangers for Savage to attack and keep them safe," Barry replied.

"Excuse me," Oliver asked. "But what's Earth-2?"

"Well, you know how we defeated Thawne, a singularity opened…" Barry explained.

"Oh, yes. And have you actually been there?" Oliver asked.

"No, but there's this Jay Garrick dude, a villainous speedster named Zoom, and a new Harrison Wells with a daughter who all claim they're from there. Pretty safe bet it exists," Barry laughed.

"I don't think that things are looking good for us right now to take a trip to another universe," Oliver pointed out. "Ray's faked his death, Damien Darhk is still at large, and if that wasn't bad enough Felicity won't stop trying to get me to tell her this secret I've been keeping. Not that she'd even react well to finding out I have a son with another woman."

"Wait, Ray's alive?" Barry asked. "Also, you just reinvented yourself as the Green Arrow. I'm surprised you don't want to move ahead in your relationship and tell her that,"

"I'm tired of romance for now," Oliver sighed. "I was a terrible person. I got a woman I loved killed three times. I pretty much ignore Laurel and Thea these days, even though they're on the team. It's almost like there's only room for one woman in my life. And I just went to visit William and his mother. It's too much to take."

"You want to visit Earth-2?" Harry's voice asked from the other room.

"Yeah, does that offend you?" Barry asked.

"No, actually. Just as long as you close the breach when you're done. Then we may never see Zoom again," Harry replied. "And we can save my daughter,"

"Huh, good idea," Barry said. "Do you think we should split up? Like, take Central City for me, and Star City for Oliver?"

"Actually, Queen, you should go to Lian Yu," Harry said. "You're dead there."

"Let me guess…" Oliver grunted. "The Gambit?"

"Indeed," Harry replied sadly, though there was a hint of laughter in his voice.

"Well, I need to talk with Iris first." Barry said.

"Aren't you the fastest man alive?" Oliver asked. "Go."

0000000000000000000000000000000000000000000000000000000000000000000000000000

Once Barry returned, Harry decided to give him and Oliver a pep talk as they stood in front of the last remaining breach to Earth-2.

"All right, Barry and Oliver, listen to me. You're about to go through the looking glass. You're gonna see things that look and feel familiar, but they're not. Up is down. Black is white, and do not let yourself get sucked in emotionally, and good luck." Harry explained.

"Alright," Barry replied, while Oliver nodded with disbelief.

Barry grabbed hold of Oliver's arm as Harry activated the speed cannon, sending the three of them to Earth-2.

"Do not get distracted by everything," Harry said, but it was too late. Even Oliver was dumbstruck by the futuristic and yet somehow retro aesthetic of Earth-2 Central City.
"None of this is even half possible on Earth-1," Barry marveled. He noticed the fully operational S.T.A.R. Laboratories. "Mind if I come in?"

"Of course," Harry said. "Though stay out, Oliver. Nobody wants to see a dead man."

"I still can't fathom that…" Oliver said as Harry and Barry entered the building. It was then that he heard a piercing noise, sounding somewhat like a very advanced version of Laurel's mechanical canary cry. The sound was a bit too much for him to handle, so Oliver quickly ran away.

"Well, well, well," A voice that made Oliver jump in fright. "Seems somebody is scared of me." Oliver turned around. It was Laurel. She was wearing dark lipstick and her hair was in a different style, but it was unmistakably her. Forgetting he was on a different Earth, he began to ask Laurel "What are you doing here?", only for her to start asking the question angrily.

"You could be an illusion. My weak side playing tricks on me. Conjuring an illusion of poor little Oliver Queen, that dead man I loved so much before I became what I am now. But alas, I am no longer Laurel Lance, nor do I have any humanity left. So if you're not a hallucination…" Laurel-or whoever she was-grabbed Oliver in a chokehold and opened her mouth wide. "WHO ARE YOU?" Laurel screamed, propelling Oliver towards Barry.

"Oliver, what was that all about?" Barry asked as he tried desperately to shake him out of shock.

"It's Laurel. She's...evil here," Oliver replied.

"That makes sense," Barry said. 'There's this villain dude, Henry Hewit, who's a normal guy here,"

"Harry was right not to trust anything on this Earth. It's all jacked up." Oliver replied. "Go get the phone book, and let's find Carter and Kendra,"

"What about helping Harry?" Barry asked.

"That can wait. Go back without me. I'll see what we came for," Oliver said.

"Okay, now you're just being stubborn," Barry replied.

"You can literally just speed me somewhere with good internet service," Oliver pointed out. Barry sped Oliver into S.T.A.R. Labs, then went to a computer.

"Won't Harry be mad about his mission?" Barry asked. "You just wanna keep an eye on Evil Laurel."

"It's just that if all good people are bad here and vice versa, Kendra and Carter obviously are," Oliver realized.

"Excuse me?" A familiar voice asked. It was Carter.

"That was too easy," Barry said, speeding rope around Carter. Of course, it was only a hologram.

"You foolish hero," Carter laughed. "You really thought you could find me, Carter Hall? The Great Hacking Hawk?"

"What do you want from us?" Oliver asked.

"My boss, Felicity Smoak, monitors the city for heroes. There's an abundance of criminals. But the heroes are scarce," Suddenly, a man in a blue hood arrived, grabbing both Oliver and Barry and dragging them to an abandoned building.

"Who are you?" Oliver asked.

The man removed his hood. It was Ray. Both were extremely shocked.

"My name is Raymond Palmer, or you can call me Blue Arrow. I ran away from my wife's company Smoak Tech to give Central City a hero, as the Flash has been missing a couple months and the Green Arrow of Star City inspired me." Ray said.

"Do you know Kendra Saunders or Carter Hall?" Barry asked.

"Kendra is my adoptive sister," Ray explained. "She hangs around Smoak Tech a lot since my wife runs it, has met Carter. You look kinda familiar, actually," He turned to Oliver.

"I have one of those faces," Oliver said quickly, putting on his mask.

"Well, I'm a speedster like the Flash. Mind if you take us to your wife's company?" Barry said. "We're detectives, and we have reason to believe there has been suspicious activity,"

"Why, certainly!" Ray said. "Though with how cold Felicity can be, she would probably be mad to see me back…"

"Let's go anyway," Oliver grinned. "After all, there's more than one way to fail this city."

00000000000000000000000000000000

Meanwhile, evil Laurel realized that Oliver and his friend had to be from another universe, like what her boss, Zoom, had said he had been to. But where to acquire such technology? She looked over at S.T.A.R. Labs. Of course. As Harrison Wells stepped out, Laurel blasted him with her sonic scream, then used his body to open the door. Quickly, Laurel ducked under the front desk, waiting for the coast to be clear. Once it was, she filled Wells with energy from her scream and opened the door to what must have been Wells' secret lab. Inside there was a mysterious hole. Had that been how the parallel universe Oliver had arrived? Laurel decided to step through anyways, excited to see what kind of world she was about to destroy.
