The next morning, Oliver and Laurel entered the bunker and they both had to admit that it was good to be home.

"It's so good to have you back." Thea said as she hugged her brother.

"Good to be back. Honestly, our little time travel adventure was interesting, but I'm glad to be back." Oliver said.

"So am I. Now I can enjoy the rest of my maternity leave before I go back to work." Laurel said and Thea smiled.

"I don't blame you." Thea said.

"So anyways, what did we miss?" Oliver asked.

"Actually, you have good timing." John said as he and Emiko entered the base, along with Winn and Roy.

"Really, why's that?" Oliver asked.

"The SCPD is tracking a new form of weaponry, poisonous bullets. They were used by the Blackout Gang to attack the Los Halcones. We could end up looking at a gang war." Emiko said.

"I'm guessing you tried to intercept a weapons buy and it did not go as planned?" Oliver asked, raising an eyebrow.

"We had to retreat. Outgunned." Emiko said.

"I would've done the same thing." Oliver said.

"Wait, what?" John asked.

"If there's one thing I've learned, it's that you can't win every fight. But you can do is take your losses and learn from them and become better. And I'm assuming that we at least got intel we can use." Oliver said.

"Yeah, the bullets were provided by Midas Medical. Quentin is working on getting a warrant to search his place." Thea said.

"I'll call Rene, see if he can expedite it, since until my maternity leave is over, he's in charge of the city." Laurel said.

"In the meantime, Winn, any ideas on what kind of poison those bullets are using. We need to figure out exactly what we're up against." Oliver said.

"Yep. Thanks to the samples Roy got me last night I was able to determine that we are dealing with Chlormethine." Winn said.

"What's Chlormethine?" Thea asked.

"It's a cytotoxic agent derived from mustard gas." Emiko said.

"How do you know that?" Oliver asked.

"I was raised and trained by the Ninth Circle, I know a thing or two about chemical weapons." Emiko pointed out.

"Fair enough." Oliver agreed.

"Anyways, the interesting part about this is that this particular chemical weapon was banned decades ago." Winn said.

"Then how is it possible that it's being used now without drawing suspicion?" Roy asked.

"Because while it was banned as a weapon, Chlormethine is still legal if it's used for medicinal purposes." Winn said.

"Medicinal?" Roy asked.

"Chemotherapy treatments, things like that." Winn said.

"And let me guess, every trail leads back to Midas Medical." Thea said.

"Exactly. It's one of the only 4 labs that still use it as an active ingredient." Winn said.

"And look at this, the buck stops at Midas Medical." Oliver said as he looked at the records Winn had pulled up.

"James Midas. I've met him at a few SCPD fundraisers, he's got deep pockets and he used them to help the SCPD." Laurel said.

"We need to bring him in." Thea said.

"We'll need more proof if we want this to stick." Roy pointed out.

"Roy, Thea, keep working with the cops, in the meantime, John, Emiko and I will work on getting legitimate evidence." Oliver said.

"What about Laurel?" John asked.

"I'm still on maternity leave not just from City Hall, but also Team Arrow until Jasmine is able to sleep through the night." Laurel said and they nodded at her.

"Wait, what about the body cam footage from the SCPD strike team. Isn't there footage of one of Midas's thugs mentioning him by name?" John asked.

"That evidence is circumstantial, since they have no way of actually proving that James Midas is the one they're talking about. We need incontrovertible proof." Laurel said, reminding them of her legal expertise.

"Let's get to work." Oliver said.

"Well, I think I know a good place to start." Winn said.

"Where?" Oliver asked.

"Something I started working back before I left Argus. It's an algorithm that can scan for chemical compositions anywhere in Star City." Winn said.

"Meaning?" Thea asked.

"Meaning that once he uploads the program to the QC satellite, we can use it to find out exactly where Midas is storing the chemicals." Oliver said and Winn nodded.

"Exactly. I'm uploading it to the satellite now." Winn said.

"If we can get proof of Midas using the chemicals to make weapons, we can get him." Thea said, right as the computers went off.

"Got a hit. It's a warehouse registered to what looks like a shell corporation." Winn said.

"Let's go. Winn, tap into the security system so we know what we're getting ourselves into." Oliver said.

"On it." Winn said.

"Let's suit up." Oliver said.

"I don't have a suit though." Emiko said.

"Actually you do. Cisco sent it over about a week ago." Oliver said as he pressed a button and a new case next to the Spartan suit opened up to reveal a silver version of Emiko's old ninth circle gear.

"Figured we'd stay with the look, just a different color." Oliver said.

"I love it." Emiko said.

"Good. Now let's suit up." Oliver said as they moved to suit up, right as Thea's phone rang.

"Hello? Yeah, okay we'll be right there." Thea said.

"What's going on?" Roy asked.

"That was Lance, an informant turned up a tip on same warehouse. He wants Roy and I to lead the raid." Thea said.

"This is good. We'll secure the evidence and wrap up Midas by the time you arrive." Oliver said and Thea and Roy nodded in agreement as they headed out while Oliver, John and Emiko moved to suit up.
