Which Doctor? Personally, I don’t mind 10 and Rose, as long as people don’t think she’s the only one he’ll ever love. He loves all his companions, and though it was different with Rose, he’s been in love before.
I actually like 9 and Rose better though. She changes him for the better and it’s beautiful. He’s really in awe of her and it’s just great. Tough guy gets softened by great girl. She’s really special to 9, she’s his first light in a long time, and she gives him hope.
