From the moment he said those three little worlds she knew it was him. It was him and not some lousy substitute. It was his smell that gave away the first clue. There was something odd about the Doctor who ran away with the broken heart. It wasn't him. She couldn't say he was a fake; he was just another person. First of all, his comment on her question sounded more than usual… redheaded. His smell somehow remembered her of the day Donna sacrificed her selves and in some way died to lead her lifeline back to where it belonged; next to her Doctor. It reminded Rose of the seconds she whispered her hidden name in dying ears.
But why? She couldn't understand. Why did both Doctors claim that the one Doctor she stayed behind with was the Meta Crisis Doctor? Why did they claim he was the clone; the substitute?
Carefully she unlocked his hand around hers and turned around to place both her hands on his chest. She pressed her ear against it and felt how the Doctor placed one of his gentle hands against her yellow hair. It was almost as if he wanted her to listen carefully. Then she heard what she was too afraid of to expect; what she with all her heart hoped – longed – for.
Thump Thump… Thump Thump… The beating of his heart was somewhat hectic, but she could understand it, since hers was racing at exact the same moment. Behind the hectic beating sound she could clearly hear the sound of another heart, a heart that the Meta crisis wasn't supposed to have…
When Rose looked up; finally forming her revelation into a solid conclusion, she saw how the doctor formed the typical smile on his face.
'There is…'Rose started.
'Something I haven't told you yet.' The Doctor finished.
