Author's Note: Second chapter. I promise it's from the same story, but it does sound a little odd at first!

-----------------------------------------------

It was a regular Saturday night for me. I was fighting another ghost- one I'd never seen before. It looked like a cross between a giant snake and a horse, if you can imagine that. It was down by Lake Eerie. Sam and Tucker were supporting me the whole way; they're such great friends. I thought I'd won. I really did. Then, the ghost jumped up and bit me- quite literally.

I fell into the water, yelping in surprise as my body hit the freezing waves. I floated back up, gasping. Somehow, I managed to force the ghost into the Fenton thermos. "Danny!" Sam called, coming into the water with Tucker not far behind her.

I smiled weakly back and waved the thermos over my head. This ghost had attacked before, in a hospital, and I'd failed to defeat it. This time, I'd succeeded. My joy quickly faded, and I winced at the pain in my chest. I looked down and saw ectoplasm covering my suit. I assumed that turning human would fix the problem; it always did. Luckily, Sam reached me just as I changed.

I yelled as the pain hit me full force, nearly dropping the thermos. I almost collapsed to my knees. Thank God the water was only a few feet deep. "Danny!" Sam and Tucker both yelled.

I stared down at my chest. I was bleeding. For some reason, that didn't register to me at first. How could I be bleeding? "I'll call your parents!" Tucker said, rushing back to shore for his cell phone.

"We need to get you out of the water," Sam coaxed me, taking the thermos in one hand and helping support me with the other.

It seemed to take forever to reach the shore. The wind picked up, making it even colder. I felt so weak and faint. I thought about changing back into Danny Phantom, but Tucker changed my mind.

As we struggled to the shore, he ran up to me, throwing a blanket around me. "Danny, the ambulance is on the way. Your parents are, too."

I nodded, smiling weakly. "It…isn't…too bad."

My chest felt like it was on fire actually, but there was no need to worry them over it. The ambulance arrived, and I struggled to stand. I'd half-succeeded when my vision began to blur. Sam's grip tightened on my arm. "What is he doing here?" she hissed under her breath.

I looked over in a daze to see what she saw. Vlad Plasmius. "Danny!" my mom cried.

My parents ran over to me. "What happened? Was it a ghost?" Jack asked.

"Ye-yeah," I mumbled weakly.

A paramedic pushed them aside. "Come on. Can you walk? We can get a stretcher."

I shook my head, taking a few stumbling steps into the ambulance with her. My mom was about to climb in when the paramedic shook her head. "We don't have enough room for everyone back here."

"But- I w-want…" I struggled to form coherent thoughts now. My words sounded slurred, like I was drunk.

"Why don't you two come after us with Daniel's friends?" I heard Vlad asked.

I attempted to glare at him, but I'm not sure if I succeeded. "I'll come, too," Maddie said. "Jack, you might need to protect the kids in case that ghost comes back."

I wanted to protest. I didn't want Vlad beside me when I was weak like this. The ambulance began moving, the sirens painfully loud. It was hard to think anymore. I felt dizzy. I only barely heard the paramedic say, "We don't have enough blood for him. He needs more than we have. That ghost destroyed most of our supply when it attacked earlier this week."

Talk about irony.

"He can use mine. I know he can use my blood; he's AB positive."

Vlad? I stared at him distantly, barely conscious. He smiled and whispered, "Hold on, little badger."

Mom was there, too, saying something, but everything was starting to blur together to where I couldn't see anything. I must've lost consciousness shortly after that.

When I opened my eyes, I was in a hospital bed. My arm hurt, and I winced when I saw the IV. Well, at least I healed super fast thanks to my ghost powers. Sam smiled down at me, stroking my right hand. "You scared me," she muttered.

I smiled halfheartedly as last night's events came crashing back in my confused and tired mind. "I'm okay," I replied.

One of the memories hit harder than the rest. "I thought they were out of blood."

She frowned. "The truck came in last night."

"That wasn't soon enough…" My eyes widened when I realized it. "Vlad gave me blood!"

"I don't care who gave you blood," Sam said. "All that matters is you're alright."

I nodded. "Yeah, you're right, Sam. Where's Tucker?"

For some reason, I couldn't shake off the feeling that something was wrong. What were the chances of our blood types being compatible? How did Vlad know my blood type? That was scary. "Oh, you're awake!"

A blonde-haired nurse walked in with a clipboard, smiling. "You're lucky," she said. "How do you feel?"

"I've been better," I muttered.

"Yes…I suppose so. It's lucky your mother and Mayor Masters were able to donate blood for you on the way here. You're type AB. Did you know that? It's a rare blood type."

I shook my head. I didn't care about my blood type. I did care that Vlad gave me blood. "You should be out of here soon," the nurse continued. "I've never seen someone heal so quickly."

I exchanged a wry smiled with Sam, trying to hide my discomfort. Maybe it bothered me more than it should, but it did bother me. Vlad was my enemy. He shouldn't be giving me blood.

I was released three days later. I couldn't get rid of the nagging thought at the back of my mind. Vlad and I had compatible blood types. Weird. Almost on a whim, I asked my father, "Hey, Dad, what's your blood type?"

He grinned widely. "I'm O negative."

That left me surprised. O negative. I was AB positive. We'd covered blood types in biology- when we were studying genetics. I had to be wrong. I wasn't thinking clearly. Jack was my father! Surely, you could take O negative blood and make AB positive, right? I thought I must just be remembering wrong. Still, I called Tucker. "Hey, man, what's up?"

"Tucker," I said, fighting to keep my voice from shaking. "I-is it possible to make AB positive blood if one of the parent's has O negative blood?"

Tucker laughed. "Doing homework? Of course not, Danny. The parents would need blood types A or B to make that."

I didn't hear what he said next. I dropped the phone to the floor in shock. No. It couldn't be true. My father was Jack Fenton. I was Danny Fenton. "Danny?" I heard from the phone.

"Bye, thanks, Tuck," I said, clicking the 'hang-up' button.

I changed into Danny Phantom a moment later and flew into the night sky. No. No. No, no, no. For some reason, the thought running through my mind was that Jack wasn't my father. Then, who was? Plasmius. Vlad is your father, a tiny voice in the back of my mind insisted. No, no, no. There was no way Vlad was my father. It was impossible. Improbable, the voice whispered again.

My mind began running through scenarios in my mind. Vlad called me 'son'. He wanted me to join him. When he made a clone, he tried to clone me- not my mother. Why me? He'd given his blood to save my life. "No!" I yelled to the empty sky.

The more I denied it, the more sense it made. Vlad's blood was compatible, and if I remembered correctly, my father- Jack's- blood wasn't compatible at all. Vlad always wanted me to be his son, after all. My parents did argue a lot, but… Vlad? "I'm going insane," I muttered.

A pink blast of ectoplasm knocked me down into a building. "Still weak, Daniel?"

I knew that voice. No one called me Daniel but him. I sighed and turned around to face him. More thoughts entered my mind. Vlad had blue eyes when he was human. I had blue eyes. We had compatible blood types. It was still impossible.

He attacked me again, and I was too stunned to pick myself up from where I sat on the roof. "What's wrong with you?" he asked.

I looked up at him with my green eyes. Vlad's hair was dark grayish-black when he was younger. My hair was black, but so was Jack's! Vlad stopped and stared at me. "Daniel?" he asked, more softly.

I just stared at him, wanting more and more to deny what my mind and heart were telling me had to be true. This was my father. I wasn't Jack's son. I was Vlad's.
