Disclaimer: Never owned 'em, never will. Seriously.
A/N: I wrote this a while back on what may have been going through the Doctor's head during the new Doctor Who first series episode "Dalek". The setting is during that pregnant pause right after Rose is locked in the bunker after being "a bit slow" and the dalek fires his weapon and just before Van Staten gets reemed into by the Doctor.
"She was nineteen years old."
His voice was flat, without apparent emotion, yet tense with it. His Rose was dead and it was his fault; not the Daleks', not Van Staten's, his, The Doctor's. As sure as he killed the Gallifreyans, he killed her, too.
He felt cold inside and his next thought intensified the feeling; what would Jackie Tyler do when he told her? A slap was bad enough; it stung, it went away. What would happen when he told Jackie of Rose's death? Jackie would probably kill him. He deserved it.
Rose, one of the most beautiful humans he had ever seen, heard, traveled with and he would never see her again. Oh, he would bring her body back to her home if he could retrieve it, but she was not there, not any more. He would never hold her; he never told her.
The pain was unbearable, his hearts shattered. He heard her die; he heard the Dalek shoot her.
He had sworn in his hearts to protect her. He swore to keep her safe.
He failed.
