"That's the hardest part about being a doctor, isn't it?" Martha asked sadly. With all the knowledge you've worked so hard to get, you don't want to think that there might be someone that you can't help…that you can't fix. You wonder what the point is if you can't cure the ones you care about…"

The Doctor could hear a heavy sigh over the phone as he wiped the tears from his eyes and quickly got off the floor of the TARDIS. "Now-now, Martha Jones…that's enough of this self-pity party. We Doctors—"

"Not yet…" he heard Martha interrupt quietly.

"We Doctorshave a very important job to do," he continued stubbornly over Martha's objection as he started checking coordinates on his screen. "The TARDIS shows me where the Universe hurts and I do my best to fix it. If I can't fix it, I do my best to ease the pain. If I can't ease the pain, I move on. It's unfortunate and painful sometimes," he grasps a switch tightly as he thinks of Rose, "But the problems of the Universe don't wait for anyone."

"That's you and the TARDIS, Doctor," Martha said pointedly. "What's my role in your grand plan, if I still have one?"

"Why Martha…I thought I made that clear when we started this conversation…you're MY Doctor." Silence greeted him over the phone as he threw a few more switches and the console began vibrating with a happy hum. "Martha? Are you still there?"

"Wha? Y-yeah, I'm still here." She answered distractedly. "Ahh…bollocks!"

"What? What's wrong, Martha?" he asked worriedly.

"I've got to go, Doctor…it's time for the exam!"

"You're okay now, right, Martha?"

Martha paused for a second as she realized the butterflies were gone. "Yeah…I'm fine now. I know I can do this. Oh…but I didn't get to tell you my story yet!"

The Doctor smiled as he strolled towards the doors of the TARDIS. "Weeellll…I guess you'll just have to tell me that one once you're a doctor, eh?"

Martha laughed softly as she replied, "I better get on it then…I've already got my first appointment!"
