So this is triumph, or

something like it: my most obstreporous block, which was flinging both folders and insults last Friday, today was docile and productive, and some were working and engaged the whole ninety minutes. Things were of course far from perfect, but it was still substantial progress over what was in the past, just last week: and I had been dreading this. After this, it's all smooth sailing, I'd say: it's all in the clear, despite the quantity of work still left to me, it will be all relatively easy to finish from here on out.
