The Doctor seemed to vunerable while asleep, He mumbled in his sleep and hugged one of Rose's arms. He looked so drainned. He was coughing and groaning. His hearts seemed to be beating more normally then they had when he was in hospital.
He slept for awhile and barely moved, He was tired and weak.
The TARDIS hummed softly, The Doctor had put in some alien planet, but instead the TARDIS had ingored that and was taking them somewhere safe.
