Jack & the doctor
The doctor followed Jack after one last look at Martha and Mickey. He really hoped Mickey would be ok.
He then sat down on Mickeys chair and looked at the computer. "Ok, let's see what you have so far", he said while going through Mickeys research.
"Alright, that's exactly what I found out so far. The message is coming through the rift. We just need to figure out how it was sent and then answer the same way", he stated and then glanced at Jack.
"Can you connect this computer directly to the rift?"
"Sure", Jack answered and got to work. A few minutes later he had plugged in all the necessary cables and returned to the doctors side, curiously peering over the timelords shoulder.
The doctor pointed the sonic screwdriver at the pc. It soared and glowed, then new data appeared on the screen.
"Aha... brilliant! Oh that is so me... Would have done it the same way." He grinned widely as he saw how exactly the other doctor had sent the message. Then he told Jack what they needed to reply.
About 20 minutes later Jack had gathered everything they needed that Torchwood had and the doctor got the remaining things from the TARDIS.
"Ok, what do we ask?", the doctor wanted to know while plugging everything into Mickeys computer.
"How to stop the virus and what it exactly is", Jack suggested. Then he turned around.
"Martha, is there anything specific you want know about that virus? We're almost ready to send a message back."
