I've got 2 questions actually. 1. How do you still know all these things 2. I can't really understand what has happened with doc scratch? How he transformed into lord english and what he did with damara (sorry if this is too much to ask, thank you so much for all the explenation, It really helped me a lot)

1. We read Hs often and check the wiki a lot. 

2. Lord English’s soul resided in Doc Scratch so once Scratch was dead, he emerged from the body. Doc Scratch intercepted the Handmaid’s meteor and raised her himself. He trained her in the clockwork majyyks and when he died she would be enslaved by Lord English and placed under a curse.
