Following Church’s death at the blades of Prometheus, Green Arrow is trying to find out what’s become of Church’s phone. His phone keeps moving all over the city, leading Green Arrow and Spartan on a merry chase. Bizarrely, Spartan’s helmet is now see-through, so you can clearly make out his facial features. I’m not sure how that’s an upgrade. I hope that wasn’t something Cisco did. They are finally led to a spot where fire spells out, “SO IT BEGINS,” both an ominous warning and this week’s title.
