No so with the girl. Yep, it was a girl going up the tree in the first scene, but she had was not, as stated in the final chapter, the first person to be punished in this way.

The way she is attached to the cone/dildo thing means that the intruders should not cause internal hemeorage (I hope) since she later ends up sold and puppyfied.

Not sure what you mean by the epilogue flashes, but yes, it was not easy to tie everything together convinsingly. Oh well. At least you stayed for the last chapter.
