dw: let's kill hitler

Why River-Doctor is my OTP...

You know that moment in “Let’s Kill Hitler” when they are about to hurt young River, and the Doctor, nearly dead, yells at them to stop?

Then, when asked, “Why would you care?”

….Literally answering the question: Why do you care? I’m not dead. 

The Doctor will care about River Song as long as he lives. She meets him for the first time in this episode and gives up immortality for him.

Your argument against this is invalid.
