Having thoroughly (but poetically) trashed her older sister, Margot turns her scathing commentary toward her younger sibling.
On the positive side, Claire appears to have moved up in the rankings, as you can tell by the description of her as "sort of nice." Contrast that to Jane, who is (among other things) "visous like a bull dog."
I haven't yet figured out if that thing on Margot's head is a crown or some kind of sailor hat.
