A few days after he returned from Nanda Parbat, Oliver got a call from Cisco.

"Hey, what's up?" Oliver asked.

"Hey, listen, the particle accelerator is actually going to be turned on this weekend, apparently Wells was able to start building it earlier on this time, but because of that, I was hoping you could do me a favor?" Cisco asked.

"What is it?" Oliver asked.

"DeVoe. He uses the energy from the accelerator explosion to power his thinking cap, which turns him into the Thinker and also later causes the creation of Cicada." Cisco said.

"So, what do you want me to do?" Oliver asked.

"I need you to destroy his thinking cap. You do that and the Thinker can never be born, which means that the Enlightenment doesn't happen, which means Cicada is never born." Cisco said.

"I'll head out to Central City tonight. Sara and Laurel's mother is out there, so I can offer for them to come with me and we can also pick up Sara's white canary suit." Oliver said.

"Great. I can't wait for the Flash to get back in action. I'm tired of pretending to tolerate Wells." Cisco said and Oliver could understand.

"Well, once Barry gets his speed, you can help him get more than fast enough to stop Thawne and considering I have some experience with Barry's speed now, I can help train him if necessary." Oliver said.

"Guess a couple of good things came out of Elseworlds after all." Cisco said.

"Yeah, but I still could've done without it." Oliver said, though without Elseworlds, he never would've had this chance at virtually a do over of his life.

It had taken little convincing to get Sara and Laurel to join him to Central City, though Oliver was hoping to get in and out of the city before the accelerator went off since he had no desire for powers. He was a self made hero, not a metahuman.

"So, where we are we going first?" Laurel asked.

"Well, you two can meet up with your mom, I have something I need to focus on alone." Oliver said and though he was tempted to see William while he was in Central City, he knew the best thing for his son was for him to stay away. He didn't like it, but William was better off without him in his life. He needed to keep him away, for his and his mother's safety.

"What is it?" Sara asked.

"Green Arrow business that does not require a partner." Oliver said.

"Can we stay a few extra days, I want to see the accelerator turn on." Laurel said.

"You can, but I plan on leaving the city before it turns on." Oliver said, since he honestly did not have a problem with Laurel getting the same powers as both Dinah and Black Siren, he did not want to get powers himself.

"Have fun doing whatever it is you're doing." Sara said as she and her sister headed towards their mother's apartment, while Oliver began heading to Jitters, since that was where he'd arranged to meet with Cisco to get the information he needed about DeVoe when he accidentally bumped into someone, causing them to drop what they were holding.

"Oh, I'm sorry." Oliver said as he crouched down to help her pick up the papers she drop, but to his surprise, he found a very familiar face looking back at him.

"It's no problem. After all, we all make mistakes." Kara Danvers said and Oliver swore for a minute he could see a bit of recognition in her eyes before it faded.

"Can we talk privately for a minute?" Oliver asked and Kara nodded as they walked into an alley.

"Do you remember ever seeing my face in person before today?" Oliver asked.

"The last time I saw your face was before I flew off trying to slow down time." Kara said and that confirmed Oliver's suspicions. This was the same Kara Danvers he knew. How that was possible, he didn't know, but for now he didn't care.

"Kara." Oliver said.

"Oliver, it's nice to see a familiar face, what the hell happened?" Kara asked.

"Why don't you tell me. What's the last thing you remember before waking up in this new reality?" Oliver asked.

"I'd just burned myself up trying to turn back time and then the next thing I know, I'm waking up in here in Central City, on Earth One, 7 years into the past and I have no idea how." Kara said.

"I think I can shed some light on that." Oliver said, causing Kara to look at him.

"How?" Kara asked.

"After you and Barry left, I went to the Monitor to see if he could change your fates. After a long conversation I don't feel like discussing, he gave me an arrow that could destroy the book of destiny, but it also had another function." Oliver said.

"It let you rewrite reality one more time." Kara realized and Oliver nodded.

"Yeah and the monitor explained to me that since you, Clark, Brainy, Lois and J'onn were all on Earth One when the reality change happened, it somehow caused our earths to fuse together, altering all our timelines." Oliver explained.

"Wow, that's a lot to take in." Kara said.

"Yeah, but Kara, I need to know, will you try to undo this?" Oliver asked.

"Even if I could, which I'm pretty sure I can't, I wouldn't. This means that my aunt is still alive, I have a chance to fix the mistakes of my past." Kara said.

"Glad we're on the same page." Oliver said.

"So what brings you to Central City anyways?" Kara asked.

"I'm helping Cisco out with something, since somehow he retained his powers through the shift and that caused him to also remember the real reality. I'm meeting him at Jitters and since you haven't become Supergirl yet, maybe you could talk to him about making your suit." Oliver said and Kara nodded.

"Not a bad idea. Though I'm still trying to figure out why the company I work for, Catco Worldwide Media is based in Central City instead of National City." Kara said.

"New reality means a new timeline, which means that something must've happened to change where it was established, but on the bright side, it means that you're closer to a certain future scarlet speedster." Oliver said with a smug smile as they began walking.

"Is it that obvious?" Kara asked and Oliver chuckled.

"A bit. You've had feelings for Barry for awhile haven't you?" Oliver asked and Kara sighed.

"Yes, okay, I have, but he was always pining after someone else and we lived on different earths. Although I guess both of those problems have been fixed." Kara said and Oliver laughed.

"Come on, let's go meet Cisco." Oliver said and Kara nodded.
