When they finally arrived to Fulham Road, the Doctor got sick again and Caitlyn only smiles as she rubs his back. "Don't apologize Doctor. It happens to all of us at one point or another. So no need to feel embarrassed. Alright?" She said in a sweet tone that let him know that she didn't hold him responsible for getting sick. After all, she supposed, everyone including Time Lords got sick one time or another. She got out of the car, and threw away the bag, walking back and opening the door for him to get out offering him a hand of assistance if he wanted it. "Let's go get your medicines." She said having seen him smile big at seeing Mickey but then get desolate again. Must be thinking about Rose and she smiles. How adorable. They loved each other, and yet because he was the last, he couldn't get comfortable with anyone. What a lonely life to go through, all by yourself. No one there to share the trials and tribulations. At least no one that would live as long as he would. But she didn't let that mood spoil her excitement about seeing the TARDIS. She would probably be as beautiful as Rose described it.
