Chuckling to himself, he climbed up the tall structure that he had placed on top of City Hall. "No more Rodney," he kept muttering to himself. "One blast and no more Rodney."

The voice came over his radio. "Heinz, what on Earth do you think you're doing?"

"Climbing," Heinz replied, climbing higher until he was on top of the structure.

"Come down!"

"No, Perry the Platypus." Heinz pulled out a remote control. "I don't think you realise what this evil man did."

"You were evil too, once!" pointed out the platypus, who was standing at the base of City Hall, staring up at his teammate. "Just come down!"

"He almost killed the world several times." Heinz checked that the missile was primed. "He needs to be taught a lesson. One that he'll never forget."

"You're going to KILL him! He won't be able to remember the lesson because he'll be DEAD!"

"He deserves it."

"He doesn't deserve it!" Perry shouted. "No matter what he's done, nobody deserves being blown to pieces! You're just being selfish and arrogant, believing that you need to kill Rodney in order to keep your ego intact. It doesn't matter what he's done, killing Rodney is not the right way!"

"No more radio contact."

Heinz took out his earpiece, hearing one final desperate protest from his former nemesis, someone he had looked up to when he first joined OWCA, before his finger hovered over the button. Some part of his brain knew this wasn't right. But at the same time, his whole body was shaking with fury. Rodney had humiliated him, hurt him, and worst of all, tried to destroy the Earth many times. He deserved it.

Down below him, he could hear Perry shouting to Harry, Maggie, and Karen, ordering one of them to stop him. But he knew they wouldn't get to him in time.

He pressed the button, launching the missile. At the same moment, something bright red flew into the missile's path. "MAGGIE!" screamed Heinz, but it was too late.

The missile hit the macaw in the chest and exploded. Red feathers flew everywhere. Even from the height he was at, he could hear both Perry and Harry's voices screaming Maggie's name. Heinz leant forward and reached out, as if trying to reach the macaw, to make sure that she was alright.

But it was clear that Maggie the Macaw was not alright.

Heinz suddenly lost his grip on the top of the structure and fell. He let out one scream before he fell silent. He knew that this was nature's way of punishing him for ending his friend's life. He was going to die, just as he had killed Maggie. He had killed Maggie. He kept repeating that aloud to punish himself. He wanted his last thoughts to be of the terrible thing he had done.

But something caught Heinz's foot just before he hit the ground. Heinz looked up and saw that Harry was leaning over from Perry's flying car, clutching Heinz's foot. The hyena's face was marked with tears but he looked determined as he let go of Heinz, who fell about five feet before he hit the concrete at Perry the Platypus's feet, fairly uninjured.

"Why did he save me?" Heinz croaked without looking up.

"I told him to."

Heinz then looked up at the grief-stricken teal platypus. "B-but why? I killed Maggie!"

"I didn't want to lose another friend," was Perry's quiet reply.

Which made Heinz feel ten times worse.

Naturally when they got back to HQ, Major Monogram blew up in Heinz's face and fired him. He confiscated Heinz's fedora and told him to pack his bags and leave.

So Heinz dragged himself to his small OWCA room and packed a suitcase. He had just packed everything up when he spotted a photo on his bedside table. He picked it up. It was a photo of Heinz, Maggie, Harry, and Karen on their graduation day. They were all smiling, clutching their brand new fedoras with the black hat bands. Heinz threw the photo aside and left the room.

Unbeknownst to him, someone watched him leave and then entered the room. The teal platypus picked up the photo and began to cry.

He couldn't help the tears as he stormed through his door and into his bedroom. He furiously threw the suitcase at his bed but it missed and hit the floor with a horrible sound, bouncing open. The yellow-banded fedora fluttered out. He picked it up, studied it once, and threw it out the window, feeling the anger surge through him. However, the anger was soon replaced by overwhelming guilt and grief.

He went to his wardrobe and pulled out a pristine white lab coat. He held it in his hands and went to the mirror, staring at his reflection and wondering how things had gone so wrong. How he could have been so stupid and wrong and idiotic and selfish and…

He slipped the lab coat on, and from that moment, Heinz the Ocelot, agent of OWCA, reverted back to Doctor Heinz Doofenshmirtz, evil scientist.

"I'm so sorry, Maggie…" was the one thing that came out of his mouth before he collapsed against the mirror, shaking and crying at the thought that would haunt him for the rest of his life: the thought that, through one single moment of pure selfishness, he had ended a life.
