Dig whistled lowly, watching Mon-El and Imra train together, both of them in D.E.O. issued jumpsuits for the time being. "You two are not pulling your punches, are you?"
"What's the point in that?" Mon-El grunted, ducking a swing from Imra.
Felicity groaned suddenly, making Dig turn around. "You OK?"
Felicity looked up from where her face was in her hands. "I have tried every trick to counter-hack what Cayden is doing, and I am completely boxed out."
"And we've figured out why," Winn gestured between himself and Querl.
"Yes," Querl nodded. "It's her fault."
Dig blinked. "Excuse me?"
Winn glowered at Querl, who blinked as well. "Was that insensitive again?"
"Brainy," Imra hissed.
Winn smacked him away, turning back to Dig. "We weren't here for this, but when you guys stopped an Internet vault from blowing up?"
"Uh huh," Dig nodded.
"It appears that that was all just a ruse," Winn sighed. "Cayden just wanted you guys to think that people were in trouble so that Felicity would break through his firewall."
"Except instead of blocking him, she actually helped him plant a virus, and because of that, Cayden James now has complete control of the entire city," Querl nodded.
Felicity nodded numbly, her face still in her hands. "A hack-cident is killing one person every eighteen minutes, and I have no idea how to stop it," she mumbled.
Winn patted her back, then looked up when he heard Oliver's voice. "We do," the vigilante said, walking up to them, with Kara, James, Slade, Malcolm, and Laurel behind him. "Thanks to Cayden James, who was kind enough to pay me a visit at City Hall."
"What'd he want?" Dig narrowed his eyes.
"He wants $10 million a day," Oliver answered.
Slade snorted. "Doesn't sound like the type of man to extort money from you, kid."
"He said he wasn't in it for the money," Kara shook her head.
"Kara's right," Oliver nodded. "That is not the actionable part. He told me the details of his son's death. He was killed one year ago today. Cayden thinks that he was collateral damage from a fight that I had in Star City."
Mon-El frowned, seeing confusion on Dig's and Felicity's faces. "I'm guessing that's not possible?"
"No," Felicity shook her head. "Oliver, you were in Hub City recruiting Dinah."
"Yep," Oliver confirmed.
"If Cayden James is motivated by revenge, maybe we can get him to stand down," Dig suggested.
"Well, I like that idea because I have no way of stopping him way, and I have no location for you to find him way," Felicity sighed.
"Brainy, can you help her on that front?" Mon-El asked.
Querl nodded in confirmation, pulling up a chair of his own. "This is not technology from the 31st century, but I know a few tricks that may help."
"We need incontrovertible proof," Oliver reminded them.
"Hey," Winn clapped a hand on Oliver's shoulder. "We're on it."
Oliver sighed and nodded, giving his friend a small smile as he joined on Felicity's other side, leaving one other computer station open for Lena when she arrived.

Dinah snarled angrily, storming back into headquarters. "I can't believe we didn't catch Vincent!"
"He had a twenty-minute lead on us," Rene huffed, following her in.
Dinah turned around when Curtis walked right past them to the computer. "Where have you been?"
"Long story," Curtis shook his head, sitting down. "I need to check on something."
He dialed on his phone, and Felicity picked up quickly. "Hey!"
"Hey," Curtis answered. "If we're still sharing intel, I need you to check on something for me."
"Yeah, shoot."
"The subway system. Specifically, where the red and gold line meet. I'm trying to stave off a disaster."
There was silence for a few seconds, then Felicity came back on. "Yeah, the automatic track signals just went offline. How'd you know?"
"Lucky guess," Curtis smiled nervously.
"You want backup?"
Curtis rolled his eyes. "Felicity, I appreciate the intel, but we're not working together anymore. My team can handle it."
He hung up the phone without waiting for a reply, and Dinah tilted her head. "Handle what?" she asked.
"Cayden James is gonna attack the subway in less than an hour," he answered, standing up. "I'd say 'suit up,' but we already are. Let's go."

"Note, keep an eye on the subway," Winn mumbled, making a note for himself.
"Hey, guys, take a look at this," Felicity called, pulling up images on the computers. "This is the city's transportation system, and these are all the accidents that have happened so far."
"A lot around the edges," James noted.
"That's the train lines and the freeways," Malcolm realized.
"He's laying siege to the city," Slade narrowed his eye. "That's why he wanted the port. He wants to block off all the exit routes and stop all reinforcements from the outside."
"Are there any roads he hasn't hit yet?" Mon-El asked.
Felicity frowned, clicking to check. "Yeah, there's one exit left out of the city, and it's the tunnel."
Kara blanched, and Oliver inhaled sharply. "William," they said at the same time, both rushing off.
The others watched them go, then Mon-El looked at Imra. "Keep an eye on the trains," he told her. "I'm going with them."
Imra nodded in agreement, turning back, taking a closer look at where the train lines met as Mon-El headed after the others, followed by Dig. "Can you guide me there, Brainy?" she asked.
"Affirmative," he nodded.
Imra nodded as well, heading off to get her own suit ready.

William peered over the top of bus seats, frowning when he saw the amount of traffic in the tunnel. He sighed, looking back down at the book he was reading, one Ruby had recommended at his dad's engagement party.
