I had a lot more trouble figuring out how to show what I wanted in this comic than I expected. I know looking at the end result, it's really simple, but I was tripping over myself to get there.
At least, I hope it's clear that Sarah was walking around them and accidentally touched Grace's hand. Oh glob what if that's not clear SARAH WAS WALKING AROUND THEM AND ACCIDENTALLY TOUCHED GRACE'S HAND I TELLS YA!
*Erhem* Anyway, yay for simulated time stop body swaps.
