After Thea had almost died due to her actions in bringing Sara back to life, Laurel had decided to give up being the Black Canary and had moved to Central City for a fresh start.
Laurel had just entered Star Labs after receiving about 10 texts to come there and to bring Big Belly Burger.
"Okay, so, why am I here right after a full day in court?" Laurel asked, dressed for court, since she now worked for the Central City District Attorney's office.
"Well for one thing, we wanted food and you were already leaving work and for another, we wanted everyone to be here for this." Cisco said as Laurel tossed him a burger.
"For what?" Laurel asked.
"For this." Caitlin said, leading Laurel into the back room where Barry was currently in some sort of contraption and Wells was running around while Joe, Iris and Barry's father Henry were all standing back.
"What exactly is going here?" Laurel asked as she passed the burgers around.
"We're recreating the particle accelerator accident that turned Barry into the Flash the first time. Now that all of Central City knows that the Flash doesn't have his speed anymore, metahumans will be coming out of the woodwork like crazy and we need the Flash back to deal with them." Cisco said.
"Barry, are you seriously on board with this?" Laurel asked.
"I have to do this Laurel. I need my speed back. Besides, Harry thinks he can contain the explosion." Barry said.
"I hope so. Because considering the number of metas already swarming this city, I don't think it can handle another surge of them." Laurel said.
"Agreed." Joe said.
"Don't worry, I've done all the necessary calculations and I should be able to recreate the accident without creating a hundred more metahumans. Ramone, we need you on the roof now." Harry said.
"I'm on it." Cisco said as he walked out.
"And you're sure we'll be safe here at this distance?" Laurel asked.
"Relax Lance. We'll be fine." Harry said, annoyed at her lack of faith.
"Really, then why isn't your daughter here putting her brain to use helping you?" Laurel asked smartly.
"Smart ass." Wells muttered as he got back to work.
"Harry, I'm in position and ready to begin when you are." Cisco said through the comms.
"Are you ready Allen?" Harry asked.
"As I'll ever be." Barry said.
"Than let's do this." Harry said as he initiated the chemical infusion.
"Ramone, we're ready for the storm." Harry said.
"Expecto Patronum." Cisco shouted as he raised the weather wand to the sky as a bolt of lightning struck it and carried down into the facility.
"Barry." Laurel said as the bolt hit, though it looked like Barry was disintegrating.
"Shut it down." Laurel said as she ran outside the safe zone.
"Laurel don't." Caitlin said, running after her, still carrying her ice cold drink.
However, suddenly a dark matter wave hit both of them and as it hit her, Laurel screamed and then the world went dark.
When Laurel woke up, she found that she was being treated by Barry's dad.
"What happened?" Laurel asked.
"You were hit by the dark matter 2 days ago." Henry said.
"2 days. Oh my god, my job?" Laurel asked.
"Relax, Joe called in a favor with the DA and you're on medical leave." Henry said as Barry walked in.
"Barry, you're alive." Laurel said.
"Yeah, and I got my speed back. But what I'm more concerned about is you. After all, not only were you hit with dark matter, but you were also in a coma. You have to have been affected by the dark matter. After all, both Wally and Jessie were." Barry said.
"Wait what?" Laurel asked.
"Wally and Jessie both have speed. We're going to have to run some tests on you to see how you were affected." Barry said.
"Okay, but why wasn't Caitlin the one treating me?" Laurel asked.
"Check out your roommate." Barry said, pointing to the other hospital bed and Laurel saw Caitlin lying there in coma.
"We still haven't found a way to bring her out of the coma." Barry said.
"But you think she'll be okay?" Laurel asked.
"Really, I'm more concerned about what will happen after she wakes up." Barry said.
"Why's that?" Laurel asked.
"Because her earth 2 doppelganger also has powers. Ice powers and she is not a nice person. But then again Cisco's doppelganger had the same powers as him and he was also evil but Cisco isn't, but still, we're just being cautious." Barry said as Harry entered.
"Ah, Ms. Lance, you're awake, good, because I think I know how you were affected, follow me." Harry said.
