It didn't kill him…
Kaplan opened his deep, blue eyes for the first time in five minutes. It almost hurt to breathe in, but he did anyways. He was surprised that he actually was breathing, which meant he was alive. The man known as Chad Kaplan listened in on what was going on inside the train from the top of it. From the sounds coming from inside, nothing was going well. His nimble fingers held on tight to the trains outer-roof, and he watched as the dimly lit lights flickered on and off. Well, it could be worse. I could be that thing's stomach contents right now, he thought to himself. He snickered his own dark joke, but soon stopped laughing. A deep, torturous pain in his left shoulder ached as he laughed, causing his eyes to water. He groaned in pain as the train kept moving forward. On his black, cotton shirt he could feel a wet spot, most likely another bite wound from the Licker inside the train.
Immediately after being ripped out from the train, Kaplan blacked out. He did not remember how exactly he got so perfectly perched on top of the speeding locomotive, or what had been going on for five minutes, but it did not matter. All that mattered to him was the fact that he was still alive. That, and helping Alice and Matt.
"Alice!" He screamed, although he knew she was unable to hear him. But he had to try. "Matt!" No one answered, as he had guessed. Slowly, he tried moving from the middle of the train, to the front, but the pain in his shoulder was too great. He slowly inched forward, but soon stopped. Well, fuck. He was a sitting duck. From inside of the train, he heard noises from fighting, and Alice screaming to Matt.
"Open the doors!" She yelled, agony wreaking in her voice. After a few seconds of near silence from on top of the train, Kaplan heard a gunshot, and seconds afterwards, a high pitched scream. He knew that the Licker had been killed. After a few moments, he passed out once again.
Waking up again, Kaplan noticed the train was stopped. He crawled to the front of the train, and from there jumped down. Another ache seared through his upper chest, and he screamed in pain. Hardly able to stand up, he heard shuffling from inside of the train. Alice and Matt walked out of it, and noticed Kaplan right away.
"Kaplan!" Alice exclaimed, relief so blatantly showing on her face. "You're alive." Chad Kaplan looked at the two of them, smiled, and checked his watch.
"Shit. Only a minute left." The three survivors, Alice, Matt, and Kaplan, quickly walked out of the train station. Passing the crates, and posts, and benches; passing the signs, and stairs, and abandoning their memories, they left the Hive. Moments afterward, Matt's arm began to mutate, and Alice nearly injected him with the anti-virus. But instead, the Umbrella employees flooded the area, Alice and Kaplan were knocked out, and Matt was taken to a research facility.
You can guess what happens next.
