The stage is set and it's pretty easy to see the ending.

1.) Biden bowed out, somewhat gracefully.
2.) Kamala is ushered in.
3.) Hunter switches his plea to guilty knowing by the time any sentencing comes, Kamala could be President.
4.)Joe pulls out the signed agreement between him and Kamala and orchestrated by Pelosi and Obama.
5.) Hunter is given a full pardon or a commutation of sentence.
6.) Joe retires and gets his Presidential library, and Kamala doesn't get the beans spilled on some of her back door issues.

I mean it's a perfect legal set up and it's been in the works for quite a while.
