While Oliver was still surprised by the revelation that Alex was actually Richter's grandson, he and the others suddenly felt something dangerous was right behind them. The four of them quickly got their weapons out and went back to back with each other to cover their blindspots.
Someone was here, and it was someone on the same level as Hektor or possibly even stronger. The only people stronger than Hektor at his full strength that are alive, were only a few. Yet all of those people were monster in human skin. The four of them who had their guards up heard footsteps echoing through the alleyway.
At the corner of the alleyway they saw a hooded figure with a scythe at hand, the scythe wasn't the typical war scythe nor was it the same as the scythe used for farming. The scythe the hooded figure carried was the same as the one the Reaper of souls carried, it was a death scythe.
Specter is Michael.
