Robin is doing surveillance on a local gang suspected of peddling mind-altering street drugs. He's hidden in the shadows on a rooftop overlooking one of the smaller, out of the way, buildings in Fire.

So far, the evening is normal and uneventful. Until he sees that flash of green out of the corner of his eye. A Green Lantern? But it's definitely not one of the three Earth lanterns he knows. He seems disoriented-- maybe he's new. Robin definitely would've heard about a GL in Keeliai.

Feel that feeling of being watched, Kyle? Because you're now being observed. And possibly even followed.
