This strip was made more complicated visually than I'd originally anticipated as a result of a couple of factors.
The first is simply that EGSNP is presented all landscapey (as in wider than it is tall), and Sarah is shrinking to 40% her normal size. This would call for being zoomed out quite a bit to actually show her shrinking and have it be readable as such in a single panel.
The second is that I am deliberately not showing Nanase in this strip, leaving what has or hasn't happened to her a mystery until the next comic. This alone made zooming out to show Sarah shrinking in a single panel work impossible, but it also made her shrinking in just two panels not work. I needed the panels narrow and tall for all of the reasons I've mentioned, which called for a third step.
So what I thought was going to be a "close up, ever closer up, one simple panel of Sarah suddenly shrinking with lines to indicate her original size" became this five panel shrinkosity.
