The Doctor met them at the Conservancy's rendezvous point at the fifth planet of the Tau Ceti star system . McGrath had received a tip from Intelligence that this quadrant was of great interest to the Aurora Cartel and could be the next target area of the Adyan raiders. It fit all the perimeters: rich in mineral wealth, lightly populated, and near an interstellar shipping lane. The planet lacked a proper name, known only as Tau Ceti E. Jens waited for his father on a rocky flat overlooking the ocean.
The Doctor's TARDIS wheezed into view and settled near Jens TARDIS, Kira. As the door burst open, Toshi ran to Jens who swooped her up in his arms. She had grown into a young woman during her time away with her grandfather. Jens kissed her and held her out at arms length. The unruly dark hair, blue eyes, and bright smile made his heart ache; she looked so much like Jack. She hugged her father again, and then walked back with him to greet the Doctor.
The Doctor was shocked at his son's appearance. Jens was haggard from the long search, and his eyes held a hardness the Doctor had not seen before. He grimly took Jens into his arms and hugged him. When he pulled back, he saw the tears Jens was fighting to hold back.
"We'll find him," he assured his son. "We'll find Jack."
Colonel McGrath saluted the Doctor. "On behalf of the Interstellar Nature Conservancy, we welcome your help in locating these marauders."
The Doctor put up his hand politely declining the salute, and walked into Jen's TARDIS joining the team at the conference table for the briefing. Two maps were spread out on the table. One was marked with previous sightings and raids. The other was marked with potential targets. McGrath reviewed the search to date. There had been one recent possible sighting in the Tau Ceti system, but no raids yet.
"Doctor, can you tell us anything about the Adyan civilization?" asked the Colonel. "There are rumors that…"
"I know the rumors," the Doctor interrupted. "It's true, Many centuries ago Adya was involved in scientific experiment by a renegade Time Lady. The Rani experimented on merging telepathic humanoids with shape shifters. Many lives were lost and the resulting civilization had such powers that they chose to isolate themselves and closed the planet for both their protection and the protection of others.
"Can they offer us any help in catching these rebels?" asked McGrath.
"Perhaps," said the Doctor. "It's been a long time since I visited there."
Jens frowned. "Why hesitate? Just ask them."
"It's more complicated than that, Jens, timeline issues are implicated. I must tread lightly." He noticed his son's anger mounting. "May I talk with you in private?"
The briefing continued as the Doctor and Jens walked over to his sleeping quarters for privacy. Jens gestured towards two chairs and a small table. As the Doctor sat down, he noticed Jack's coat hanging on a hook near the door.
"Where have you been?" Jens asked coolly. "It's been over a month since Jack was abducted."
The Doctor was silent. "The education of a Gallifreyan is complex, even delicate. I was in the middle of teaching your daughter some of the basics required of a Time Lady, and I couldn't interrupt…"
"Jack is her father," Jens glowered.
"She knew what was happening." The Doctor shifted uneasily.
"She knew and did not come?" Jens was incredoulous.
"Jens, you have never had formal Gallifreyan training," the Doctor began. "There are things we know about timelines and the vortex that…"
"I do know this," Jens interrupted. "You don't abandon the ones you love." He stood up and turn his back towards his father fighting to stay calm. "But this is Jack. You've always had a different standard for Jack."
He turned to face the Doctor. "You left him on the Game Station after he gave his life for you, and then you let him rot one hundred and fifty years on Cardiff without knowing what was happening to him." Jen fumed. "When you did see him, you ran! Next you set him up for a year of torture on the Valiant, then you dropped him off again in Cardiff to pick up the pieces. He needed you during the 4-5-6 when he lost his grandson and Ianto. The Miracle damaged the planet, made him mortal, a target for the families, and yet again you were not there.
The Doctor looked away.
Jens was shaking with anger. "But this is Jack," he said sarcastically. "This is the man who waited for you, the man who trusted you, the man who always tries to do the right thing no matter what the personal cost . And now you are telling me you are training our daughter to treat him the same way you do? How dare you!"
"Jens, please…" The Doctor stood and put his hand on his son's shoulder. Jens shook it off.
He moved closer to the door, lightly fingering the coat, and then turned to his father. "If this is what being a Gallifreyan means, I want none of it!"
The Doctor put his head down. "I'm sorry, I can't explain now…"
"Can you at least go to Adya and talk with their leaders." Jens eyes held back his tears. "Can you at least help us find him while you are here."
The Doctor took a deep breath, paused, and then nodded.
"Good, I'll tell the team," said Jens in curt reply. He started to move towards the door.
"Are we good?" The Doctor asked. "Me and you?"
"No." Jens turned and looked at his father. "We're not."
