The Doctor.

The Doctor knew his fait, he was going to die… and his beloved wife was the one.

River, his wife. She didn’t want to kill him obviously, why would she? She loved him. This religion called The Silence had kidnapped her when she was a baby and brainwashed her to be a weapon, she was owned by them. She broke free years later with the help of the Doctor and they fell in love… however they don’t have a happy story. The Silence found her again and caught her. They put her inside a space suit forcing her to be unable to do her own thing, the suit controlled her.

They were met on the beach, River in tears as she tried to fight back against the suit, while the Doctor is ready… she had to do it… she had too.
