Spinel had been patient enough.  Scaring two people wasn't as good as scaring everybody, but her invisibility power wouldn't last forever and beggars couldn't be choosers.

In her best 'ghost' voice, she said "Johnny forgot to strap me to the roof and I fell off, and you left me back in the canyon!  Whatever will I dooooooooo?"
