I doubt it was exactly ten seconds, but it's not like Carol was standing there with a timer. That also gives me wiggle room for claiming what the effective ratio is between Sarah's perception of time and how much time has actually passed while using the spell.
The spell that simulates stopping time, allows Sarah to interact with thing within that simulation, and in no way is a glimpse into the future. I would like to emphasize for no particular reason.
It would be exaggerating to say I had to make this comic twice, but not by much. I was close to completing its inking when I discovered a new and exciting error I had never encountered before (and one that was simply referred to as "unknown error"), and the last time I had apparently saved was mid-sketching the second panel.
That isn't like me, or at least, I thought it wasn't. I even have a save shortcut as a dedicated button on my tablet. It's been a long time since something like that's happened to me, however, so maybe I'd gotten complacent.
In any case, faced with the prospect of staying up late while having a cold, I decided to redo my work the next day. This was surely a calmly made decision that involved no cursing whatsover.
