"Pretty sure. You could keep dropping it a few more times, see if it always-or-usually does something weird or if it just drops normally sometimes?"
"No, the pen, see if it repeatedly bounces and whatever. Not conclusive or anything but it should at least help to show it wasn't just a mistake, if it wasn't."
"Yeah?" responds Ev. "I can do that."
She drops the pen a few more times.
