Another awesome story. I like how you mentioned how fragile time is because of the paradox machine and how the Doctor was dreaming about the future. It sucks that the Master died. I wish that the Doctor would've been able to keep him in the TARDIS, but I guess later on the future he does with Missy staying in the vault. It helps to know that the Master will come back as Missy and that he's not permanently dead.
