Disclaimer: I don't own Martha, Donna, The TARDIS or The Doctor. I would be so beside myself if I did though! No all of them belong to the genius behind it all.

A/N: So heres where I usually would say why I chose to write this, but I think I'll save that for next chapter. Oh and if you didn't guess there is some spoilers for season four sort of. The spoilers being Martha and Donna being the next companions, but most of us knew this. And I should probably mention I'm American and I'm being good and not watching the rest of season three online. So if I happen to put in something that was clarified in season three, just ignore me. I fully intend to use the "I am American" excuse.


When the Impossible Becomes Possible

Summary: The Doctor, Martha and Donna once again find themselves traveling the universe, exploring its infinite possibilities. But even the Doctor knows there are limits. Until a familiar friend once again finds themselves face to face with The Doctor, all bets are off.

Chapter One

"So Martha Jones where in the universe do you want to go?" The Doctor asked with a manic grin.

"Oh you know me. I'll go anywhere I haven't before." Martha replied excitedly

"How does the Restaurant at the End of the Universe sound?" The Doctor already began to spin knobs and flip switches.

"Sounds great!" Martha had just returned to come traveling with the Doctor again. She was a bit surprised to find he had another companion, Donna Noble, with him so shortly after she left. But she was just happy to be traveling with the Doctor again.

"I can't remember if they have banana daiquiris there or not. I haven't had one in so long. Let me tell you Martha, bananas are good."

Suddenly the TARDIS began to hum and shake violently. Martha and The Doctor held on to the console as tightly as they could before being lurched backwards.

"Something's not right." The Doctor said as he carefully moved around the console.

"What the hell is going on?" Donna called as she stumbled in the room.

Before the Doctor could answer the TARDIS came to a forceful stop.

"Stay here." He said as he grabbed his tarnished jacket and headed out the door. Martha and Donna gave each other the same, "yeah right" look and followed him out. As the door opened a barren red landscape stood before them. The sky was a familiar light blue, but was spotted with dusty brown clouds. The Doctor stepped out, hands jammed deep inside his pockets. "Don't believe I've been here before." He mused to himself.

"Oh God we're on Mars aren't we?" Donna moaned

"No I've been to Mars and trust me, this isn't it." He replied suppressing a laugh.

Suddenly a hooded figure emerged from an obscure bolder. "Doctor?" The voice asked. It was familiar, but the Doctor had a hard time placing it. "Doctor?" The figure asked again.

"No it can't be. It's impossible." The Doctors eyes widened as the figure drew nearer.

But it was possible. The figure removed their hood and revealed them self to the bewildered Doctor.


I know its a bit short, but the chapters get longer so tell me if you want me to continue! There is a method to my madness!
