The artifact was placed upon its shelf and the warehouse gang, the Doctor, and I were all sitting in Arties office. I left my seat and stared out the window overlooking the warehouse. After a few minutes I turned to stare at my friends. "I have to leave."

"It's alright, we'll see you later." Pete said.

I shook my head and looked above them. "No, you won't. I've been here to long as it is. I'm ruining your world; if the Doctor and I don't leave soon events will happen that disrupted your world's timeline."

"What are you saying? You can't just leave us!" Myka shouted.

"I have to, I don't belong here. Don't you understand my being here was a fluke. I should have left a long time ago and never have come back."

Claudia stood and her face was full of anger. "You're not a fluke! You saved my brother and you saved our lives more times than any of us can count. Maybe you were brought here for a reason."

"Claudia you must listen. Every time I come here the hole between my world and yours shrinks. If I stay, all the life's I'm supposed to save, end. I was never meant to be here." The Doctor stood and pointed to the exit. I nodded and watched him leave. "I'm so sorry."

They all got up and hugged me. Tears were in all of their eyes, even Arties. Claudia tried to hang on to me, but finally let go. As I walked to the door I stopped at a table and placed my Farnsworth down.

I opened the door to the TARDIS and was met with stares but no one spoke. The Doctor must have told Amy and Rory what happened because neither of them asked about my different appearance. I walked towards the console where the Doctor was leaning. "Can we stop somewhere before we leave?" He nodded and moved aside so I could get to the controls.

When we stopped the Doctor opened the door. I could hear the birds chirping as I walked through it out into a green cemetery. I stopped in front of a small grave marker and fell to my knees.

I closed my eyes and began to cry. I was shocked when I opened them to see a red rose. I turned towards the person holding it to see the Doctor with a sad smile.

"I never told him how much he meant to me."

The Doctor didn't say anything as he sat next to me. He stared at the marker for a second before he pulled me towards him. "I'm sure he knew."

I let him hold me for awhile before I turned towards him and placed a kiss on his cheek. "I wouldn't know what I'd do without you, Theta." I stood up and wiped my butt off. "Well I've got to get changed and we have trouble to get into." I winked at the Doctor and skipped back to the TARDIS.

If I had stayed behind, I would have seen the Doctor touch his hand to his cheek and slowly slid it to his lips. I would have also heard him mumble, "Nor what I would do without you."

But I didn't, instead when I nearly fell out of the giant closet trying to lace a pair of converse, I was met with the Doctors trademark smile.

Handing back his jacket, I gathered around the console with Amy and Rory, and wondered where the mad man with a box would take us next.
