The two folds at the bottom of 3a (which meet under her forefinger) are on two adjacent creases of the central hexagon; the red edge under her middle finger is the (red) mountain fold connecting these two creases (one of those drawn in 2a, under either of her fingers).
It is a bit like folding half a fish base (rabbit ear!) and flipping the resulting small triangular flap to the left.
(Note that, here, this isn't a triangular flap because the edge of the paper is circular).
Then, you need to add the valley fold shown on the red part, starting at the right from the bottom of the drawn mountain fold, and going up and left to the end of the next mountain fold (crease not drawn) on the border of the paper.
You probably want to precrease that valley fold before folding the rabbit ear though, so that it is easier and more precise.
Not sure if it's clear, sorry!
Please ask again if you don't understand me...
PS: Her nickname is Mélisande*, with only one 's' and a '*' at the end.
