After the war, he felt like he was just floating, alone in the vast emptiness of space. But after he met Rose Tyler, he could feel himself becoming ground to Earth or whatever planet they were standing on. Everytime he felt like he was going to drift off somewhere where he didn't want to go, he would grab her hand and could feel himself grounding. The feeling of skin, the way she grabs his, almost as if knowing what would happen if she lets go. Every tongue touch smile, every laugh, every tease and flirt, The Doctor could feel himself staying grounded more and more each time. Rose Tyler, the pink and yellow human, kept The Doctor grounded to Earth.
