Isaac started to walk down the tunnel again. Without a train, the would be a good hour by walking or thirty minutes by running. A slow jog, Isaac started to ponder if the team will wait for him. He also wondered if they could some-how catch a train without any power. Isaac looked up to see a few more lights were on. The city had limited abilities of moving electricity to different districts. Otherwise, it was a chaotic and disunited utilities system. The new lights created small circles of clear light in the center of the tunnel. A little ways apart, they didn't make a clear path while making the outside areas seem all the darker. In the far distance, a few exit signs could be seen but usually lead to abandoned complexes or other walkways.

Isaac continued to jog until he found a small object on the ground. The tunnel was almost completely clean of debris when he trekked through earlier. He picked it up. It was merely a small but heavy piece of pie for... water or some kind of fluid. Still wet and dripping, the pipe must broken above and yet, he couldn't see any trails of pipe on the walls nearby. Isaac shook it off as not important and continued on. At one point, he passed a couple large vent entrances about the size of Isaac himself.

Isaac only peered into the vent for a moment but heard a distinct sound of a tool dropping. Isaac's body shook for a moment. He was disorientated only for a few seconds. When he regained his wits, he thought he saw some movement where his light ended. Isaac turned and began to jog down the tunnel at a much quicker pace. A few moments later, and he could hear another sound from the vent just like heavy footsteps yet there was second noise. It sounded as if someone was dragging a tool on the side of the vent. He finally heard some light pounding on the vent cover.

Isaac was in no mood to find out. He started to run down the tunnel. Isaac realized he was starting to have another panic attack. His legs started to feel numb. With a some-what desperate 'No', he kept running. Aim forward, Isaac's flashlight picked up on yellow tape. He was too panicked to realize what it was for a second only to find it the back of the train.

Suddenly, he heard the vent cover fall to the ground with a huge thud. A second waves of shaking traveled across Isaac's body. Distinct sounds of running could be heard behind Isaac. Isaac pounded on the back door of the train. With a little control, he grabbed a marked safety bar and threw it to the side. The door slid open.

Isaac jumped on the train and turned around. He still heard someone running towards him. On the verge of a panic attack, Isaac grabbed another bar on the door and slammed it shut. He turned around in the darkened train and sprinted to the end of the car through an open door. He sprinted through the second car and stopped. A light just appeared in the train car. Another light switched on. The power was returning?

The person by the back of the car was pounding on the door. Isaac turned around to run through the third car but it was closed. It was stuck without power and couldn't be opened. Isaac jumped around again. The person stopped banging on the back car. It was running around the side of the train!

Before Isaac could see the silhouette through the window, something struck it. A few splinters of glass struck Isaac harmlessly but enough to make him throw his arms up and duck. The window didn't break but there was huge crack on the window. The person was banging then on the windows of the third car.

Isaac was relieved for a millisecond and jumped two feet in the air at the same time. The doors for the third car slid open. Not bothering to look who's banging on the window, Isaac sprinted through the cars again. Various lights were turning on as well as the television playing static. Isaac kept sprinting till he saw the train's control car door. Locked too, Isaac had to use his card.

Isaac struggled with his belt until he found the card. He sliced the security lock a number of times until it lit up. The doors opened and Isaac rushed in only to hit his head on the curved glass in the cock-pit. Isaac fell back in pain both hands on his head. He regained control of his now spasming body when he heard the glass break in the third car. The window was shattered and Isaac could see glass flying across the car. The car also shook when the person threw himself in the car. The silhouette of the man was extremely blurry.

Isaac looked around the cockpit for a second until he saw a newly lit emergency lock door. He punched it once to have the door seal almost instantly. Isaac could see the strange silhouette in the back enter the light for a mere moment. Isaac body now achieved almost complete muscle failure. Isaac fell to the floor with a mild thud. Before loosing all sense of the world, Isaacs head started to roll around and felt his body being pulled back.
