Bellatrix is organising as the force who will take over, heavy emphasis on blood purity (unsurprising), but that actually makes her a better ally to Rod with his creepy dynastic castlebuilding (only blood lasts) than they have been in a while.
There's clearly a subset of DEs who want to keep being horrible people (see conversation about Yaxley).
Barty and Tosha reveal that they are relieved to be free of the Mark.
Bella wanted Tosha to "turn himself in", Tosha is communicating with her in friendly fashion in the journals, ish, but will not object to her turning up dead. Barty appears thrown in entirely with the DE side, Tosha is less clear to me.
Tosha appears to not have issues with blood status among people raised in wizarding community but may have muggle/muggleborn problems. Various people are poking his buttons to see which way he may jump. (Siz, Sally-Anne, and Justin - "father" and "patron" are in his latest, according to Google translate, my! - but I think also Rachel got him, with the 'the people I'm with have been working for years to protect children from people like you' line.) I am deeply curious to see how that plays out for sure.
Montague appears to me to be cheerfully playing both sides in order to see which way he wants to jump. I hope Rachel is assuming that's what he's doing. I hope Bella isn't.
The DEs seem to be amusingly underestimating Rachel.
Alice wants less mayhem. I'm not sure she's likely to get her wish, there. The Order/remnants of Dogstar cooperation appears solid, though I wonder how much is left other than Inderpal and Haruman at this point!
Justin appears to have an assassination target.
Also, the last aftermath thread was nearly full of comments.
