I followed my sister into the TARDIS, smiling, as Donna adjusted the monitor of the console and pottered around the controls. Both of us didn't notice the Doctor leaning against one of the coral beams, sorrow in his eyes.

"I thought we could try the planet Felspoon… just cos'," Donna said conversationally with a bright smile on her face. "What a good name, 'Felspoon.'"

"What's there?" I asked curiously as I leaned back against the console but out of my sister's way.

"Apparently it's got mountains that sway in the breeze," Donna told me excitedly, gripping my shoulders for a moment in her excitement and I couldn't help but laugh. She let go of my shoulders and moved around the console again, still chatting away, "Mountains that move. Can you imagine?" She twisted a knob.

"And how do you know that?" The Doctor spoke quietly and I looked at him surprised as he hadn't said anything since we've returned to the TARDIS.

"Because it's in your head!" she answered as if it was obvious. She grinned at him, "And if it's in your head, it's in mine."

"And how does that feel?" The Doctor asked, still in that quiet voice, as he straightened up and started to move towards my sister slowly.

Her grin widened while she moved about the console, a small skip in her step. "Brilliant! Fantastic! Molto bene! Great bit of universal packed into my brain. You know you could fix that chameleon circuit if you just try and hotbind the binary." All of a sudden, she began speaking so fast that I could barely understand her and my eyes widened, "Binary, binary, binary, binary, binary, binary, binary, binary, binary, binary, binary, binary, binary, binary, binary, binary—"

"Donna!" I exclaimed, stepping forward and gripping my sister's shoulders. She took in a sharp intake of breath and she let it out shakily, letting out,

"I'm fine!"

I turned to the Doctor, still gripping Donna's shoulders, "What's happening to her?" He didn't answer me, "Doctor?"

He took another step forward, focused on Donna.

"Scar, I'm fine," my sister reassured as she gently took my hands from her shoulders. She went back to what she was doing with me watching her every move, "Nah, nevermind Felspoon. You know what I'd like to meet? Charlie Chaplin. Shall we do that?" She asked, taking a glance at me and the Doctor, "Shall we go meet Charlie Chaplin?" She picked up the phone and spoke into it, her voice going back to that fast pace that she had before, "Shall we? Charlie Chaplin? Charlie Chester, Charlie Brown. No…" She placed the phone back on the console, "He's a fiction, friction, fiction, fixen, mixen, rixten, brixton—"She gasped and doubled over as if she was in pain. I hurried over to her and held her in my arms as her hands held onto her head.

"Oh my God," she breathed out.

"Donna?" I questioned concerned and confused to what was going on.

"It's okay, sweetheart." She brushed my bangs away from my eyes, forcing a smile on her face but it looked more like a grimace. "I'm fine."

"No you're not, Donna," I said stubbornly. "What's going on?" She averted her eyes from mine and I decided to try the Doctor again, "Doctor, tell me what the hell is going on?" I demanded.

Again, I didn't get an answer. He was still focused on Donna and I wanted to pull my hair out.

"Do you know what's happening?" he asked my sister.

She didn't say anything for a moment. "Yeah," she gritted out, obviously not wanting to admit that she knew what was wrong. If only they would tell me.

"There's never been a Human-Time Lord metacrisis before now," The Doctor said in a low voice. "And you know why."

I felt something wet drip down my arm and I looked up to see that Donna's eyes were moist with tears. "Donna," I whispered, reaching up to wipe away the tears that were threatening to fall down her cheeks. Something was horribly wrong. That was what I knew for sure even if I had no idea what was happening. My sister flinched away from my touch and she gently pushed me away before standing up shakily. As soon as she was on her feet, she spoke up quietly to answer the Doctor.

"Because there can't be," she said. She averted her eyes from the Doctor and pretended to be busy with the controls, "I want to stay."

"What do you mean?" I scoffed, "Of course you're staying." My sister met my eyes for just a moment. She looked so sad and my heart dropped to my stomach.

"Look at me," The Doctor said to Donna softly but she didn't.

"Doctor? What is she talking about?" I asked when I saw the opportunity to speak. For the first time since coming back here, he looked over at me and met my eyes. The same kind of sadness was in his eyes that Donna had. I've seen the sadness before in his eyes. It was the sadness he got when he would talk about Rose. Before I could say anything, the Doctor broke his gaze from mine to meet Donna's but she still wasn't looking at him.

"Donna," he said her gently. "Look at me."

She finally did and her voice was shaky as she whimpered, "I was gonna be with you … forever."

"I know," The Doctor whispered gently.

I stood off to the side, not knowing what to do.

"The rest of my life … traveling … in the TARDIS. The Doctor-Donna. With you and my sister." There was a moment of silence as a look of realization appeared on Donna's face, "No. Oh, my God." She began shaking her head frantically, eyes filling with tears as she backed away from the Doctor but he just simply walked towards her. The urge to protect my sister came over me and I grabbed onto the Doctor's arm.

"Leave her alone!" I said loudly, giving his arm a hard tug. He stopped, "Whatever you're going to do to her, leave her alone!" He didn't make any move so I let go of his arm and stood in front of Donna where she had stopped backing away but she was still shaking her head, the tears now falling down her cheeks.

"I can't go back," she managed to say. "Don't make me go back. Doctor…" she pleaded, moving to stand in front of me.

"Donna…" I tried to grab her arm but she took a step forward, making me miss her arm.

"Please," she continued in that pleading voice. "Please, don't make me go back."

Go back? Go back where? I hated not knowing what was going on. With me not knowing, I didn't know how I could help so I did the only thing I could do. Stand there and watch what I would learn would be the most heartbreaking thing I would ever have to go through.

The Doctor placed his hands on Donna's shoulder, looking the saddest that I had ever seen him. "Donna. Oh Donna Noble." He sighed sadly as he looked into her eyes, "I am so, so, sorry."

From where I stood, I could see my sister's body trembling as her head snapped up to look at him.

"But we had the best of times," he whispered. "The best. Goodbye."

As soon as my sister started panicking and repeating 'no' over and over again, I had a feeling that the Doctor was going to do something and that feeling only intensified as he placed his fingers on her temples, closing his eyes. "Doctor! Stop!" I cried but it was too late.

With one final 'no!' my sister fell forward into the Doctor's arms and he held her close. I didn't let him hold onto for long as I rushed forward and took my sister from him, holding her tightly while glaring up at the Doctor.

"What did you do to her?" I snapped.

"She's just asleep," he said vaguely, moving towards the console. "We need to take her home."

"No, not until you tell me what's going on!" I exclaimed, tightening my grip on Donna.

"I'll explain everything after we get Donna back home." His tone left no room for argument but I didn't get a damn! He was going to tell me what he did to Donna whether he liked it or not!

"I said no. you're going to tell me what's going on before you take her anywhere." I gave him a heated glare and gripped his arm with one of my hands while I kept a hold of Donna with my arm before he could take one more step towards the console.

He breathed heavily through his nose and stiffly nodded at me. I let go of his arm and returned it to wrap back around Donna. The Doctor looked me right in the eye as he spoke in a soft voice.

"I had to erase her memory of me and her travels … everywhere we went," he said. "She took my mind into her own head and it …" He took a deep breath before he went on, "was killing her. I'm taking her back home. She can't stay here. If she remembers me, she will burn up and she will die."

I stared at him for a moment. "There's something you're not telling me," I said slowly. "What is it?"

"Nothing. That's it."

"I'm not stupid, Sky-Guy!" I growled. "What are you not telling me?"

"Scarlett, you don't want to know." His eyes looked pained as he shook his head at me.

"Tell me!" I demanded. "Tell me. Now. I'm not a little kid. I can handle it."

He let out another sigh and looked away from me. Silence filled the air after that but it didn't last very long.

"I'm so sorry, Scar …" he whispered, still not looking at me. "When I erased her memory of me and our adventures, I had to … erase her memory of you…"

My body went cold as an icicle and I breathed out shakily, "W-w-what?"

"I had to, there wasn't anything else I could do."

I didn't say anything as I sunk down to the floor with my arms still tightly around my sister but I moved her so she was laying on my lap. The only thing that was on my mind was the fact that my sister wouldn't remember me…

I holed myself in my room after the Doctor took Donna back home. I could have went with him…but I couldn't bare the thought of my sister waking up and not remembering, so I stayed in the TARDIS to keep from experiencing that heartache.

I hide myself in the covers, crying with tears dripping down my cheeks and on the sheets of my bed. I probably would have cried myself to sleep if I didn't hear a knock at my door.

I didn't even want to get up to answer, but the knocking continued, and I forced myself out of bed to open. It was the Doctor.

A coldness swept through me at the sight of him. I could barely even look at him. He noticed.

"Scarlett…please."

"Don't…" My voice shook. "How could you?!"

"I'm sorry…"

My body started shaking. "Sorry doesn't even cut it! How could you do this to me?! To my sister?! Just when she thought she was something, you had to rip it out from underneath her! Donna didn't deserve it, and you don't know it!"

"What was I SUPPOSED DO?! LET HER BURN!" The Doctor yelled at the top of his lungs and I would have flinched if I wasn't so angry and hurt. "DID YOU WANT HER TO DIE?!"

"OF COURSE NOT!" I yelled right back, my face turning red. "But I didn't want this! My own sister won't remember me, all because of YOU!" I was in his face now, screaming. I hit his chest repeatedly. "I HATE YOU!" I kept screaming this with every hit to his chest.

Before I could hit him another time, the Doctor grabbed my hands and pulled me towards him roughly. I tried to get my hands out of his grip, screaming at him still.

To stop my screaming, he did the last thing I expected…he kissed me roughly. Emotions were raging and it was only natural this happened, but it was still shocking.

Though I knew it was wrong, I kissed him back heatedly and before I knew it, we were in bed together.

Waking up the next morning, I was alone and the Doctor was nowhere in sight. I quickly remembered what happened. I groaned to myself. Why the hell did I do that?

But I was wrong about him not being there because he was. He was sitting down in a chair beside my bed, shirtless but he had his boxers on. The Doctor stared at me, guilt in his eyes for what we both did.

With the anger gone, I realized that I shouldn't have gotten angry. My sister was his friend...and he was just as upset about having to get rid of Donna's memories of him and me as I was about the situation.

My eyes teared up a bit. "I'm sorry..." I whispered.

Immediately, he went over to me and gathered me in his arms, forgetting that I had no clothes on. I decided to just ignore that fact as I snuggled against the Doctor, burying my face into his chest, letting tears fall down my cheeks and onto his skin.

"No...I'm sorry..." he whispered in my hair. I just shook my head, still crying. "I promise you. Donna will be okay. She's safe from harm...nothing's gonna happen to her...your grandad will keep her safe..."

I felt reassured but I hated that Donna wouldn't remember me. I closed my eyes tightly and let the Doctor continue whispering reassuring words against my hair.

Despite what happened between us, something that was never mentioned again, I still decided to travel with him and I hoped that I wouldn't regret it as we began a whole new set of adventures.

TBC...

In...

The Sequel to DROMP!

Which will consist of the Tenth Doctor special episodes. ;) BTW, I need title suggestions! I just decided to put the specials in a separate story so any suggestions would be great! So tell me them in a review.

About this chapter though, yes the Doctor and Scarlett slept together, which I've been planning ever since I started this story so I'm really happy to finally get to it. This does change things between them, which will be apparent in the sequel.

And Donna's officially gone...I'm going to miss writing her, but of course, she will continue being mentioned. Promise. And she will be seen again as you know with the End of Time. :) So that's a good thing. It's still sad though and she will forever be missed...

Anyway, please review and I'll see you in the next story!

PS. Ten Too and Rose did not kiss. In my mind, he met Pete World's Scarlett later on and left Rose to be with her. HAHAHA
