Author's note: Over the last few months against my better judgement and at the convincing of my little sister I decided to give the shows another shot. Supergirl so far has been an improvement compared to last season the story has a direct narrative, Kara is back to being the strong yet heartfelt woman that was lacking in season 2, and she's back to confiding her issues and concerns with Alex again which has always been the centre of the show. Arrow so far has a lot of issues right now but the fact they've brought the focus back to the original 3 again and got rid of Cayden James, he was awful as a villain which is a shame as I'm a huge fan of Michael Emerson, I'm willing to overlook those issues. I got the idea for this story after reading the Arrow novel 'Fatal Legacies' which serves as a midquel for the end of Arrow season 5 and the beginning of season 6.

He ran as fast as his legs could carry him panting as deep as his breath could catch. He thought it would have been an easy job rob the bank make off with millions given Supergirl was missing since last night he though it would have been like taking candy from a baby. But that all changed when his guys were suddenly picked off one by one by this freak. They had no idea who or what it was but they knew one thing the ferocity in the way it fought the way it was ruthless proved it was not Supergirl and, luckily for them, the fact it didn't kill all of them with laser eyes proved it wasn't the black suited Kryptonian either. Whatever it was it was something else. He decided to bolt after one of them got killed trying to take a hostage, but this thing whatever it was didn't settle for that. It wanted all of them punished.

He rounded the corner going down the alley his feet skidding to a halt as he realized too late that it was a dead end. A sudden thud echoed through the alley whipping out his pistol and turning around he saw it, the thing from the bank.

'D-dd-don't come any closer!' he trembled raising his gun but before he could get a shot off or even blink an arrow whizzed by and knocked the gun away. He quickly raised his hands in surrender as the figure walked forward drawing another arrow from his quiver.

'Please!' He begged fear and terror in his voice. 'You don't have to do this.'

'Yes, I do.' The hooded figure answered coldly.

'Why?' he asked.

'Because you have failed National City.' Those were the last words spoken as he raised his bow and fired.

24 Hours earlier

Star City, Earth-1

Oliver had just tucked William into bed, these last few months he'd finally gotten his son into a routine sleeping schedule which was easier said than done after the tragic situation with loosing Samantha due to the actions of Adrian Chase. At the start William sleeping soundly was next to impossible most nights he'd wake up screaming from nightmares other nights he wouldn't sleep at all but finally after much effort his 10-year old finally slept as well as a new born. While that was a memory none could forget, something so tragic as loosing a parent who could, the path to healing was yielding results not just in William's life but in Oliver's own as well.

Oliver thought about where his life was now ever since that horrific event just mere months ago and how for once it was a well-adjusted life. He was a newly married man, he had a son he was finally in a close relationship with, his friends and family were alive, and aside from the city being in crisis from the attacks by Cayden James and the recent falling out he'd had with the newbies life was surprisingly going well.

Oliver mused at the circumstances of it all as he walked to the bar in the apartment kitchen to make himself a drink. Felicity had gone to escort her parents to the airport, Dig was at home celebrating the holidays with Lyla and JJ and Thea went to make sure that Quentin was doing alright and not drinking at a bar after the mixed feelings he no doubt was feeling due to his earlier abduction by Black Siren.

Suddenly a rhythmic beeping noise caught Oliver's attention before he could take a sip of his bourbon. Oliver made his way to the bedroom where he opened the drawer where the noise was coming from, then taking the device emitting it in his hand: his interdimensional extrapolator.

After the Dominators, Cisco had given a device to Kara Danvers so that she could breech over from her Earth if they ever needed help with another alien invasion or if they had special occasions like Barry and Iris' wedding. Cisco in turn gave a device to his team, Barry's team and the Legends on the off chance one of them needed to call for Kara's help if the others weren't available. Ever curious Oliver activated the device as the hologram of a familiar auburn-haired woman appeared with a look of obvious distress on her face.

'Alex, what's wrong?' Oliver acknowledged wondering why the woman he had only met at Barry's wedding last week was calling him of all people, if Oliver was being honest if he was expecting anyone from this transmission it would be Kara.

'We need your help.' Alex said in a way that did not sound like a request.
