The Doctor was still sleeping, he indeed was afraid of losing her, He sometimes wasn't sure if seeing her and Jack again was all just some dream he was stuck on, he breathed deeply and tried to stay relaxed.
"Rose..," He sighed in his sleep.
Jack nodded and was listening to her, He thought she was rather smart to have worked that much out. "Wow your good." He chuckled. He kissed her "And hope so, Plan to travel awhile in the TARDIS."
He hoped the TARDIS would be ok with him in time.
