Battle of the Worlds

Flashback(Earth-1) Enter Black Cat

(Arrowverse Earth-1)

"So......" Cisco began when he saw both Oliver and Diggle step back into the cortex, clean and better than how they first came. "What was all that about?"

"Somebody stole his purse." Oliver said pointing at Diggle.

"And him having a stolen purse has anything to do with both of you covered in wet cement and paint?" Felicity asks looking at the two.

"No that happened after we gave chase to the person who stole the purse." Oliver said not looking at the rest.

"But still doesn't explain the wet paint and cement." Barry said and he got a glare in return from the Emerald Archer.

"But really what happened?" Peter asks.

(Flashback to few hours prior)

"I can't believe they are not in Star City." Diggle muttered as he weaved through the crowd coming back to Central after doing investigation back in their City. "Not only that many of the street thugs and low lives are just coming to Central City too. Why?" He angrily ate a doughnut that he had brought while looking at Oliver who had his eyes someplace else.

"I don't know." Oliver said not removing his gaze from where he was looking too. "But whatever it is it's not good." His attention turned towards a shop which was showing the latest news on the Flash, Kid Arachnid and Speedy, showing the fight between the Demons and Barry and Thea, before it turned back to Kid Arachnid pulling a large trailer as moment later a train passed below him, followed by the crash of vehicles.

"That kid has a lot of power." Diggle muttered beside him as he watched Peter drag the trailer up by himself. "Remind me why exactly were you worried about him?"

"Because he is a kid and he should be enjoying his life not fighting these guys with that sort of weapons." He pointed towards the scene where the brute jumped out of the van.

"The kid is like you and Barry, Oliver." Diggle said back in return. "He has a guilty conscience enough for both of you, stopping him from helping people will not help him either, so let him do what he does, we can only watch over him and make sure he is okay."

"Very difficult to do when there are people made specifically to kill him." Oliver said as he watched a young girl, probably around Peter's age stumble into Diggle.

"Sorry!" The girl quickly said before looking at Diggle with an apologetic look. "I am in a hurry!" Before she could move away, Oliver caught her hand.

"You can go after you give my friend his wallet back." Diggle turned to look at Oliver in surprise and so did the girl. He quickly checked his pockets to see that he was indeed missing his wallet. A smirk settled on the girl's face surprising the two.

"Oh, and what if I don't?" The girl asked in return.

"Well we could leave you to the hands of the law." Diggle began.

"And I will just fork it out just because you are threatening to call police, could be entertaining though." She paused for a moment. "But to hand me over you have to catch me first." She said and Oliver was sure he saw something with her eyes, the next thing he knew that she was waving away with both of her arms as the two looked at her in surprise.

"Huh?" Diggle muttered confused as the girl began running.

"Close your mouth and get her before she disappears." Oliver said as both began running after her. She quickly turned a corner both of them doing the same quickly, only to find that they had stepped over wet cement.

"What?" Oliver looked down confused, they just came from this side a few moments earlier there was no work going on here.

"Where did this come from?" Diggle asked confused.
