A/N: I saw this story awhile ago, written in French and I loved it, and I thought that others should have the opportunity to enjoy it as well. So I PMed the author, Duam78, and asked if I could translate it, and they agreed. So without further ado, Double Vortex!

Disclaimer: Neither I, nor Duam78 own Stargate SG1 or Doctor Who. This is translated from the fanfiction written by Duam78.

Chapter 1: A Common Problem

The Doctor, once again, had saved the planet Earth. This time, from a Sycorax threat. It was time for him to set out again towards new adventures. He had just finished Christmas dinner which he had shared with his friends: Rose, Mickey and Jackie. A true Christmas dinner.

Then they went outside to look at snow falling on London. However, after the Doctor's explanations, the snow proved to be ashes of the Sycorax vessel which the Prime Minister Arietta Jones had ordered destroyed. It was a bit less romantic now.

The Doctor walked towards the door of the TARDIS. Rose, who did not know he was going to ask her to accompany him, was anxious. He had regenerated; changed physically and his personality was a little different. Would he still like her?

"And you? What will you do now?" Rose asked him.

"Um well… I will return to the TARDIS and my small life," he replied.

"All alone?"

"Do you want to come?"

"Yes!"

"Really?"

"Yes!"

"I thought that… because I changed…" the Doctor trailed off.

"I thought that because you changed…You wouldn't like me anymore..." Rose said, also trailing off.

"I would love it if you came! You want to, right?"

"Of course."

They remained that way a moment, motionless, looking at the sky. Then Jackie interrupted them.

"You two are insane!" she cried. "Both of you just go looking for trouble!"

"The troubles are only the beginning!" said the Doctor happily. "So many things await us up there. It's all new for me! All those planets… those creatures, those horizons, which I haven't seen yet. At least, with these eyes. And it will be… Fantastic!"

The Doctor held out a hand to Rose, inviting it to take it. Rose hesitated, this hand still frightened her. The Doctor had lost it during the duel and it had completely grown back…

"Where will we start?" she asked.

The Doctor pointed a finger towards the heavens and indicated part of the sky. "Um… That way… No, wait… That way!"

After saying goodbye to Jackie and Mickey, the two companions entered the TARDIS. The Doctor automatically threw his coat on a support beam, and moved towards the control column. Rose dropped hers into a seat and approached the Doctor.

He had entered the coordinates of the destination which he had chosen but had fun not answering Rose who kept asking him where (or when) they were going.

When all was ready they were on their way. The TARDIS traveled through a vortex in time and space, this time in direction of New Earth. Suddenly, the TARDIS was shaken by turbulences and sparks flew from the center console.

"What's happening?" Rose cried. "Doctor?"

"I don't know…"

The Doctor scanned the screen anxiously. What was going on? He had never seen anything like this before. It seemed like the vortex that they had just borrowed had crossed through another vortex! He decided to stop the engines as well as the vortex generator and to try to materialize somewhere he could examine the situation.

Meanwhile, elsewhere…

Sloushh! The vortex generated by the Stargate had just closed again. Team SG-1 returned from P3X-774, what appeared to be a technologically underdeveloped planet, but which had brought its batch of surprises to the four travelers. After having undergone attacks it snake guards of Apophis which had killed them, they had "awoken" in the village of Nox; peaceful people, whose level of technology, especially in the field of medicine and invisibility, was extremely advanced.

The Nox had refused to share their knowledge, preferring not to involve themselves in the conflicts of others. The Nox had a primitive appearance; a kind of fusion of humanoid beings and the vegetation. Not being able to convince the representatives of this race to agree to form alliance between their two people, SG-1 had set out again towards the Stargate and had crossed the vortex in direction of Stargate Command.

The return voyage was done without a problem for the team, they'd had enough practice by now. It had already been a few months since they had begun their voyages of exploration through the galaxies, and for them, to cross this "vertical water barrier", was like passing under a sheet of water. Upon their materialization on the approach ramp, General Hammond awaited them. He seemed anxious.

"Lucy! I' m home!" crowed O'Neill with his usual sarcastic good mood.

"Colonel!" said General Hammond professionally. "You had a problem?"

The Colonel's three companions looked at their superior questioningly.

"General?" asked Major Carter.

"That made three hours that we waited since your last message informing us of your return!" The General informed them.

"You're joking!" O'Neill said in his usual way, but hurried to add a "sir" at Hammond's stern look.

"If I then to allow me," put in Dr. Jackson. "It didn't seem to me like we had the least problem during the return voyage."

"Indeed, Daniel Jackson," Teal'c agreed.

"I'll launch a program immediately, sir," Carter offered. "To analyze the operation of the Gate!"

But before she could move towards the stairs leading to the control room, anti-intrusion alarms went off, flooding the departure bay with a red light.

"Close the iris!" Hammond ordered Sergeant Siler, who was in the control room behind the protective window.

"It's not coming from the Gate, General!" Siler called.

"What do you mean it's not the Gate?" O'Neill hollered over the siren, deeply confused. "What the hell does that mean? Where else could it come from, Siler?"

The siren blared over the whole Cheyenne Mountain Complex.

"I don't know, colonel!" Siler replied. "But I am sure, that it's not coming from the Gate!"

A/N: There are a few things different that I had to change and tweak a little for it to make sense in English. If you can read French, I encourage you to read the original. Anyway, I hope you liked my handiwork, don't forget to review!
