Chapter 30-31: Was there a more sophisticated basic idea than appearing to be incompetent, then playing possum? I'd have expected one of the other two armies to expend a second (double tap) sleep spell on the downed, given that Neville came up with the same tactic later on.

Also, nice touch writing Neville as Bean without using a sledgehammer on the parallel.

ETA: It took me a bit to understand Draco's particular revelation: that Quirrell made sure to place all the other smartest students (and the other candidate generals mentioned in Ch. 29) on Sunshine.

As I argue in the reviews for chapter 31, Hermione herself was surely not playing possum, and likely neither were her 6 soldiers. That was not their idea. (Whether Nevile is smart enough to tell Harry, or whether one of the other armies will think of it in time for battle 2, is a question for the future.)

There were 24 people per army, and 11 of Sunshine came at Harry and 12 at Draco. And Harry & Draco had their realization of what happened when they remembered that Sunshine's soldiers went down immediately at the first shot. They were playing possum (all but Hermione, who didn't want to risk it).

The 6 soldiers left is after the battle of Sunshine's return, after they've already taken Potter hostage.

I increased the number of soldiers Hermione had left to help make this clearer.
