Jack looked at him in confusion. Unsure what brought that guess. But maybe he should check the TARDIS. "Alright. If you're sure. I'll go check the TARDIS." Jack kissed the Doctor real quick, slipping on his now dry over coat and heading for the TARDIS.
When the TARDIS had brought up the planet's image and name, Arwen looked at the screen curiously as she read the information about the planet. "Galli-frey? Interesting name. Sounds familiar somehow...I guess I was born there?" She had been reading the information while she leaned on the console. "You must have been with the Doctor a long time then." She smiled. She heard the TARDIS' door open and turned quickly to see a male walk in. She smiled when she noticed it was Harkness. The immortal smiled after folding his arms and shook his head. "I was worried about you. The Doctor guessed right." He told her. Arwen sighed and felt that she was in trouble for going off alone and being in the TARDIS without the Doctor's permission. "Sorry. I woke up in the middle of the night and couldnt go back to sleep. I thought I would wander and ended up near the TARDIS. So I came inside, I was talking to her when she showed me some info about a planet called Gallifrey. I been reading." She explained to Jack in hopes he wasn't mad. Jack walked up toward her and the console. "It's alright. The Doctor and i were worried. You could have left a note." Jack said as he hugged the young adult. Hugging him back, the female Time Lord felt a bit better, knowing she wasn't in trouble.
