The final bell chimed, signaling the teenagers' realease from their prison of education. The students burst through the doors of Gotham Academy and streamed into the court-yard. They filed into the waiting limousines and Bentleys. Every one wore the same blue-yellow stripe ties, dark navy blazers, dress shoes, bleached white shirts, and finely pressed trousers- plaid skirts for the girls, caki pants for the boys. They also acted the same: texting on their iPhones, chatting in groups and cliques; acting like average teenage kids.
Amidst the swarm wandered a single girl, his target. From his watch point in a tree across the street -cloaked in invisibility-, Seeker caught glimpses of her several times before she disappeared into the mix of her peers once again. He finally locked onto her position as she was talking to a group of girls before turning to a taller boy with wavy blonde hair. They walked together to a white motorcycle, streaked with gold, and drove off on the vehicle, the girl's hands looped around the boy's belt.
Seeker leapt out of the tree and ignored a small white poodle as it barked noisily at the still-invisible man. He kept the cloak up until in the driver's seat of his Honda, then reappeared, glanced at the picture of a younger version of his target pinned to the sun-visor, and drove after the teenagers.
---------------------

Declan finally detected the motorcycle and its riders three cars ahead of him at a stop light. He continued following them, always keeping two cars between them, occasionally falling back farther to avoid apprehension.
Eventually, the bike pulled over, parked in front of apartment complexes, and Declan was forced to follow them on foot. It was slightly easier having more freedom to move about, yet more difficult to keep up with the quick paced teenagers. They slipped through the street cluttered with pedestrians with ease, obviously having much practice in the city life Unfortunately for him, Declan wasn't used to so many people in his way and had to struggle through the mass of people.
As far as he could tell, the boy and his target were friends, maybe something closer. They chatted as they walked and the girl laughed often at her companion's witty jokes and friendly jibes. The laugh was familiar to Declan, something he had heard before.

The two boys sat on the cream-colored couch, watching their parents dance to the Christmas music from the stereo. Their father twirled his wife, earning an easy, gleeful laugh from the woman. He brought her close and lowered her in a dip, his stormy grey eyes sparkling.

Declan blinked away the memory. He had to search a moment for his targets. They had progressed through the crowded street and suddenly turned into an alley.
Caught off guard, Declan shoved his way through the crowd. He stumbled into the alley, only to find it empty. A shift if the shadows caused him to glance up just in time to catch the glimpse of a shoe before it disappeared onto the rooftop above.
Without a second thought, Seeker re-cloaked, and, with a running start, sprinted up the wall. He grasped the ledge of the building and pulled himself up into the rooftop. He glanced around and spotted two figures sprinting across the rooftops. One was completely clad in a black body-suit, navigating gracefully across the buildings as a bird flies through the sky, her braid streaming behind her. The second was flying on a sort of wheelless skateboard. He was half crouched over the air-craft, gaining speed. His golden blonde hair whipped in the wind.
The invisible predator took of after his unsuspecting prey. He was able to move quickly and easily over the obstacles and gaps in the apartments and restaurants thanks to his years of training. But the other two figures were equally quick, the boy easily speeding ahead on his hover board and the girl keeping up with him with ease. Seeker was able to gain but ten yards between them before they suddenly dropped into an alley.
He cursed and sprinted faster to the ledge, but saw no sign of his targets as he peered down into the alley.
"Malediceres fortuna!" he exclaimed in frustration.
