This page was an experiment in trying to illustrate the superhuman speed of this new villain.  In case it isn’t really working for you, the idea is that she manages to scoop up the boy in one arm (without impaling him), pivot back toward the window, slash through the fire extinguisher and leap back out the window, all in a fraction of a second.

Some parts of the page work better than others, I think.  I like the staggered format of the top panels, but I’m not sure if the blurry artwork conveys the speed, or if it just looks sloppy….
