"Come on, Alex," the Scout shouted to her. Alex caught up with the scout again and they hurried into the base.
"Wait a second," she said, stopping before they were fully inside. "Isn't this a bit strange?"
"What do you mean?" he asked.
"Wouldn't someone from the other team be here right now?" she asked. "I know you're usually ahead of everyone, being the fastest, but you're going slower because of me, and we stopped to get that other scout. Stay here for a second," she told him, getting out her disguise kit. Once she used it, the scout was a bit confused.
"So you don't fully transform with that thing?" he asked.
"Like I said, it's different from the Spy's kit. Both teams see me the same way, so there are still a few differences in appearance so our team can tell us apart, yet in the short time that the other team could get a close look at me, they won't be able to tell the difference."
Alex walked into the opposing team's base and looked literally everywhere; in corners, down hallways, and so on. She was being pretty paranoid, but it was probably worth the time. Soon, she walked into the trap. The enemy Pyro was hiding above her, and came down moments after she passed below him. After a small amount of being burnt, she'd fallen. Of course, the Scout noticed this.
He ran in with his scattergun and began shooting. The Pyro turned around and started attacking him, knowing already that he'd been fighting a Decoy before. The scattergun wasn't much compared to the flamethrower, although it was enough. As soon as the Pyro was distracted, Alex scrambled to her feet and pulled out her knife. She was able to stab him in the back, similar to the way a Spy would.
"I'm not even going to try to count the ways you're similar to the Spy. It's a little creepy," he said.
"Well, my strategy works. Besides, even you were convinced that I was killed," she smiled. "Anyway, paranoia is my thing, so I'm usually pretty cautious about planning and whatnot."
"You really should've warned me about that, though."
"Well, you know about that now. I can take more damage than you, so if I'm disguised as you, I can fake death and attack when their backs are turned," Alex told him. "But I'm still pretty beat up after that, and I don't think the Medic is going to be over here any time soon."
"You should go back then," he said.
"Don't worry. What's the worst that could happen? If I get killed, I'll just get respawned. There's nothing to really be afraid of." She spoke a little too soon. As the two turned the corner, they realized getting through would be harder than they thought.
"There's a sentry gun in there," the Scout said, hearing the faint beeping in the open area.
"Well, it'll take me a minute to think of a plan to get past that… although you'd probably have to wait up for me afterwards. We can't both make it through."
"Or," said a voice behind them, "you could let me handle it." It was the Spy, of course. "The Red Engineer is probably up there with his little toy, so it would be nice to have a bit of backup, if you wouldn't mind," he mentioned, his accent making him sound a bit more intimidating than Alex expected.
"Okay," she responded. "How exactly are we going to do this?"
"I'll go and put a sapper on the gun," the Spy said, "and then you two will need to come out and start shooting it, or the Engineer. I'll try to get him, but it'll be the end of all of us if he fixes the sentry, so try to destroy it."
"Alright," she sighed, still a bit nervous about the plan.
Moments later, the Spy cloaked himself and headed toward the sentry gun. It wasn't too long before the gun's power was draining, and shots were being fired. The Engineer, however, was killed seconds before his sentry gun was destroyed.
"Ha!" the Scout shouted, "Broke your stupid crap, moron!"
"You have no respect for other people, do you?" Alex asked, emotionlessly.
"No, he doesn't," the Spy replied for him.
"The enemy has taken our intelligence!" the announcer shouted.
"Shit," Alex said, "come on, let's get their intelligence and get out of here."
"Sounds like a good idea to me," the Scout said, grabbing her hand and running down the stairway towards Team Red's intelligence.
"You couldn't have given me a warning?" Alex shouted, trying to regain her balance.
"Well, hey, we're stickin' together for the mission, and we're in a hurry, aren't we? Besides, you didn't warn me earlier." Alex didn't respond. They ran into the large, open room. In the back corner, there was a small metal desk; on top of it was the briefcase. The Scout grabbed it, and they heard the usual announcement, although they heard also something else.
"The intelligence?" a voice yelled. It was the Red Soldier. He started coming down one of the hallways towards them, although he hadn't seen them. They hurried back out through the other hallway.
"Keep going," Alex whispered, "I'll lure him away."
"You sure?" he asked.
"Absolutely. It's not like I can take much more of this before I get picked off." Alex stopped running and turned around. She ran back towards the hallways where the soldier was. She started yelling and shooting at him, and just making a hell of a racket. The second the Soldier noticed, he greeted her with a shot from his rocket launcher, which she was easily able to avoid at the other end of the hall. Once he was out of the hallway, he was able to follow Alex a bit farther away from the intelligence room, where she was quickly finished off by a rocket that actually hit several feet beside her.
However, because of the respawn, she knew perfectly well what was happening around her. The Soldier walked over to where she was, and soon realized his error.
"Damn," he shouted as usual, "It was just the Decoy." He turned and headed up the stairs, back into the base.
When Alex was respawned back at her base, she came out up on the second floor, where the Sniper was aiming at the enemy just across the way. She walked out into the open a bit, but he'd already noticed her.
"Have you lost you're mind, sheila?" he asked, quickly shoving her back behind a metal wall, then aiming quicker than she thought possible. "If you stand out in the open up here like that, you're going to get sniped," he took a shot, "like that."
Alex was speechless. "Go on, find the others. That's what you were going to do, wasn't it?" Alex nodded and hurried across and back into the base.
"The enemy has dropped our intelligence," the voice announced. Alex was relieved, but she still hurried. She ran down onto the first floor and then out of the base, where she was greeted by the other team's Demoman. She pulled out her gun and began shooting, about to run towards the Red Team's base. Then, she saw the Scout, waiting up where the enemy Sniper was a few moments before. He was pointing back above Alex. She knew what he was trying to tell her, seeing a small, blue light moving around by the Demoman, who wouldn't stay still.
She had to get him to stop moving so the Sniper could get him, but she had a better idea when she heard a few other members from her team. Alex ran back inside, and the Demoman stayed put. He was aiming bombs up at the Sniper, who was forced back inside. That was her chance. She pulled out her disguise kit and changed into the Sniper.
Alex could hear her team coming out towards the Demoman, so she waited for them to pass by. The Medic, the Heavy, the Pyro and the Soldier all ran past her, into what she knew was a trap. Alex didn't tell them, though. It's not like it mattered, since they'd be respawned, and she wanted to stick to her plan. She followed close behind them, just close enough to be injured in the blast. Of course, she wasn't close enough to the bombs when they went off to be killed, although she was close enough to fake it without anyone knowing.
The Demoman stood over the others, looking away from Alex. "They're goin' to have to glue you back together," he shouted, "IN HELL!" Suddenly, he noticed the mistake he'd made, but it was too late. He'd been stabbed in the back of the head.
"Funny," Alex said, changing back into herself, "I thought we were already there." She picked up her knife.
"Nice one!" the Scout shouted as he ran past, grabbing her hand. They ran back inside, but soon realized that the Demoman was playing as a Decoy. While he kept the team busy, the Red Engineer went through the sewers and built up a sentry gun in the Blu Team's base…
