Robert turned to the army Digimon and then pushed a button on his digivice causing what looked like a ball with a mouth full of zigzag teeth and exaggerated lips. While the firewall will prevent things like this from being going past it, it didn't protected it from being manifested inside. It's basically the same thing as a virus hitching a ride on another program to bypass a firewall. Well this virus was Zeta_2 and part of what he called his Zeta series made to help with infiltration, Zeta_1 was built to track people Zeta_2 on the other hand... was built to cover up other programs or in this case: A large cloud of smoke came out from Zeta_2's mouth covering the room in a inky black fog. 

Losing the target meant [Death Behind] would fail as they needed to know were the behind was. Sealsdramon looked around blinded, these people were annoying him he could see a single thing, but there was one thing he could track them with, the wingbeats of Doru. He closed his eyes to focus on his sense of hearing. Quickly picking up the sounds of the winged Digimon moving to his left before nothing, he was going to land and when he does that was his chance. He waited until he heard a giant thud and then used [Death Behind] once again, the knife wielding Digimon instantly closed the distance bouncing off the wall and landing behind the enemy and then calculating the size and location of the purple wyvern he swung what was supposed to be a fatal blow only for his blade to meet the air rather than anything solid.

The confusion only lasted for a moment as the swing of the knife brought enough wind to sweep away the smoke to reveal the trickery. It revealed a dedigivolved Doru and a Robert holding up a his digivice with a microphone app. They grinned as The purple dinosaur opened his mouth. The assassin Digimon knew that this range would be extremely damaging even if Doru was now at the rookie stage, he needed to get away from the duo before Doru unleashed his attack, but it was two late as the two was already done charging their attack as if for dramatic effect both of the shouted in unison.

"[Hyper Dash Metal!]"

Sealsdramon had barely enough time to bring up his arms to defend himself from the cannonball. The attacked swept him off his feet and sent him flying back sending enough wind pressure to sweep away the smoke cloud in it's path, causing the army Digimon to crash into the back wall causing it to crack in a spider web like pattern, replacing the smoke cloud with a dust cloud instead. Robert smiled exactly as planned.

The dust cloud scattered and in it's place was a Digimon, but it didn't look like Sealsdramon. It was much smaller around the size of Doru and the rest of the rookie Digimon. It's skin was a navy blue camo pattern, it had the equipment of a standard military infantryman M16 included, however it was covered in scratches and bruises and all of it's equipment was cracked and cut open in places. The arms was the worst of the damage as they where leaking streams of red data. This was Sealsdramon's rookie form, Commandramon. The radio on Commadramon's combat vest flared to life as a feminine voice came out of it.

"Delta! Delta! You hear me what happened?"

The Commadramon now known as Delta responded back to the voice, looking at Doru and Robert cautiously, though they weren't making a move as they were more confused then anything.

"I ran to some trouble just before the target. I need you to digivolve me to Tankdramon."

Robert was shocked that meant that this Digimon had a human partner, but Doru wasn't having any of it, he couldn't let this guy digivolve further he needed to stop him. Doru got ready to pounce on the wounded Digimon, but the voice on the other side of the radio yelled out in disapproval.

"No! It's too risky in your current state, we're pulling out."

"But I-"

Delta was interrupted mid sentence by the girl who said adamantly.

"No you are getting out of there and that's final! I'm using the return program. Oh and you two, next time don't get in our way."

Before the two of them could react green code surrounded the army Digimon before disappearing and taking the Digimon with it. It would seem their adversary had gotten away. Though it did hammer in a fact that was discussed earlier. They weren't the only humans in the Digital world, it would seem their were others and not all of them were friendly. Robert sighed they weren't going to get much done if they stood around here. Robert took out a sandwich from the digivice and handed it to Doru, they might need to digivolve again, so it wasn't a bad idea to keep Doru's energy up.

"Well then time to get back to the important part." 

The white haired hacker told his partner. Doru quickly snacked down on the sandwich, before licking his lips and walking towards the door side by side of the white haired hacker. They stood infront of the double metal doors of the terminal room, as Robert connected it to his digivice and hacked the doors open. As long as there wasn't anymore complications. This would be one objective complete.
