This is written for my friends, who came up with a new ending. This starts just after Captain Hammer fires the death ray.

It was fast. He flew. He died. Simple. Dr. Horrible lifted himself from the floor, noticing Penny standing in the corner.

"Billy?" she asked.

Dr. Horrible hung his head, "Penny, I'm sorry."

"Billy, I can't believe it. You were so nice," she said with disbelief.

"Penny, I am. I just- He- He took everything. Everything I ever wanted," Dr. Horrible managed to say.

Tears ran down her face. "I loved him, and you destroyed him!"

Dr. Horrible walked toward her slowly. "Penny, did you really love him? It looked like he was embarrassing you up there more than anything. Did you love the man, or how you thought he saved you?"

"What?" She asked, "How could you say I don't love him? He saved my life."

"Listen to what you just said. You said that he saved your life. It sounds like you love him because of what he did for you," explained Dr. Horrible, "Penny, he didn't stop the van. He pushed you out of the way, but I stopped the van before he even touched it. I was holding the remote."

"Billy? You saved me?"

"Yes."

"Billy, I- I don't know what to say. You are this? All those times we ate frozen yogurt together, you were evil? And still are?" said a confused Penny.

"Sort of," Dr. Horrible admitted.

"It's a lot of information to handle."

"Penny, listen to me. I can be good. I will do whatever you ask me to. I would do anything for you, I love you, with all of my heart, soul, and mind," proclaimed Dr. Horrible.

"Billy... Or should I call you Dr. Horrible?"

"Whatever you would like to call me."

"Billy, I love you too."

She leaned in for the kiss, and it was perfect. They pulled away looking into each others eyes, and began to sing.

There's good in everybody's heart

Keep it safe and sound

With hope, you can do your part

To turn a life around.

I cannot believe my eyes

Is the world finally growing wise

'Cause it seems to me

Some kind of harmony is on the rise

Horrible: Take it slow.

Penny: You look at me and seem to know

Horrible: The things that I'm afraid to show

Penny: And suddenly I feel this glow

Both: And I believe

There's good in everybody's heart

Keep it safe and sound

With hope, you can do your part

To turn a life around.
