When River first met Xiao Shi in the library, many things about them were recorded in her notebook, which means that they had experienced many things together, but Xiao Shi still didn't know who she was. In the play, she also said that the more she knows about doctors, the less doctors know about her, because their timeline runs backwards. In this episode, the doctor saw her for the first time, but it was her last time to see the doctor. Later, she existed as a computer consciousness.
The actress of The River once read an article in a BBC special program, explaining the timeline from her perspective. I will post the original text and my simple translation summary to you.
Summary: River was kidnapped at birth, and her name was Melody Pond. She was brought up as a secret weapon to kill the doctor, was thrown to new york and was reborn for the first time. Then she grew up with Amy and Rory as Mel and watched them fall in love, but at this time she only knew that she was going to kill the doctor, not knowing that she would become a river song in the future. She gave the doctor a poisonous kiss and the doctor died. But at this time, she found that she would fall in love with the doctor in the future, and what kind of life would be like a river in the future, so she saved the doctor with her remaining rebirth energy. At this time, the doctor gave her a Tardis diary. Let's meet again at different time points in the future. We can compare and see the time points of two people. Later, Silience wanted River to put on a spacesuit and kill the doctor. But at this time, she didn't want to kill the doctor any more, so time and space collapsed, which means that the original time and space were carried out in the order of doctors' death. In order to save time and space, the doctor had to escape from his own death and let others think that he was dead, so River was arrested as the killer of the doctor (she would go back every time she escaped from prison). From this time on, her timeline is opposite to the direction in which the doctor started.
Original text:
I was born in battle, on an asteroid called Devil's Road. I'm the daughter of Amy Pond and Rory Williams. They named me Melody Pond. I was kidnapped and taken to an orphanage on earth by the silent servant Kovarian.
I was raised for one purpose: to kill the doctor.
I escaped from my spacesuit and lived on the streets. Homeless, lonely to die. Until I am reborn.
Be the best friends of young Amy and Rory. Growing up with my parents. Waiting for the doctor to arrive. Then I will generate a new form. I am the woman who will become a river song. Although I didn't know it at the time.
I was born to kill doctors. I did it with a kiss. A kiss poisoned by the Judas tree. But I saw who Hege was, and I saw how much I loved him. So I used the rest of my life to restore his life. Because I know that doctors are worth it.
In return, he left me the best gift. (refers to a blank diary. ) I know that one day I will find a doctor. We saw her go to the archaeological school. ) But the spacesuit is waiting for me.
But I just couldn't bring myself to kill him. In this way, all the time collapsed. Only a doctor can save the universe.
Rule number one: doctors lie. He escaped his own death. A secret I know I have to keep. Even if it means going to jail. But I've always been good at avoiding it.
From this point on, I realized that I knew more than him. At this point, we saw her tell Rory that she couldn't stay with the doctor until the end, and then they met as adults at Demon's Run. )
From that moment on, we lived in the wrong order, the doctor and me. In all our future meetings, I will know him better, and he will know me better.
Until one day the doctor will invite me to see me kill him. Once again, I found myself in the Silent Lake and returned to my own timeline. This time, he witnessed the process of the doctor being shot and knew everything, but he couldn't tell those who cared about him most that the doctor would survive.
Go back to the orphanage where I grew up, but this time as a witness to my own escape. Shoot all the silence in the tunnel. Did I mention that I am kick-ass with a gun? No one can kidnap me and get away with it.
Then his first kiss and my last kiss.
But I always knew that as long as I left him a message, the doctor would be by my side. (refers to the giant carving in the cliff. ) He will always be there to catch me. (flying out of the spaceship. ) Even when the Byzantine Empire collapsed, he came, and my love was irresistible-he brought a Amy Pond who didn't know me.
Then we see Amy and Rory drinking wine with River in the garden. ) I finally let Amy know this wonderful secret-the best man I know is still alive. No matter how happy they are, I know a worse day awaits me: my last visit to the doctor. I always knew that one day my lover would not know me. Now I look into his eyes and see that this day has come.
Doctors are willing to sacrifice themselves to save the library. But I have to take his place. But that man, the impossible man, never gave up. The doctor saved me and saved me in the computer. All my good memories of the doctor will last forever. Because sometimes, everyone is alive.
