Hazel knew that the Leighton family had this resort in the hill of the mountain where one side of the scenery was the mountain, while the other side was the forest. And if you walked a little further, you would find a cliff where you could see the sea and hear the sound of the waves from there. The wedding itself would be an outdoor wedding.
Well, probably Hazel could use that cliff to push Arlo down when no one saw. Even though that couldn't happen.
It would take a miracle if she had a chance like that. But a girl could dream, right? At the very least that was a plan so it couldn't be said that she neglected her attempt to get revenge on the two of them.
Another thing about the guest list for the wedding was that while the Leighton family had a cooperation with the Barlowe family, the Leighton family had some kind of bad blood with the Lozen family, which meant Arlo couldn't bring Aubrey with him.
