Funshine can see the dumpster that he knows Flicker is in. He can see the rooftop that Terawatt is on; but since Terawatt hasn't checked in over comm, Funshine doesn't know that yet. Terawatt is directly above Flicker, and Funshine is directly across the street.
EDIT: Flicker is in a dumpster on the south side of the street. Terawatt is on the roof of the building on the south side of the street, directly above Flicker. Funshine is in a ventilation shaft, behind an intake screen, on the north side of the street, above twelve feet off the ground. The Fin and the SOCorp officers are in the middle of the street, taking cover behind the east side of a cop car. The Shifter and Lovelace are about fifteen feet away from the Fin, behind an ambulance. The burning warehouse is about sixty yards down the street to the west. The party has neatly flanked the Fin and SOCorp commanders.
FURTHER EDIT: Flicker and Funshine are extremely well hidden, and will not be seen unless they do something to reveal themselves. Terawatt has not yet been spotted, but will be if he persists in peeking over the edge.
