I haven’t read this week’s part yet so I’ve been avoiding the thread. 
In general though I do try to read towards the beginning of the week so I can follow along with the discussion. I don’t know about process, but if I don’t know a word by context I’ll look it up and move on. Sometimes I’ll create flashcards.
I haven’t had to look up a lot of words, of which I have created a total of 2 flashcards over the first 4 weeks. I do make note of character names and their readings and descriptions, though. 
It’s natural that discussions slows down after the first few weeks. But it’s probably especially striking after the really lively first week(s) for this book.
