the POTUS dies/removed/whatever, then the VP takes over. Something happens to her, it goes to the Speaker of the House, the President Pro Tem, Sec of State, and so on.
This is also not how it works. If POTUS dies/is removed, VP becomes POTUS and chooses a new VP. It would only got to SotH if the VP died/was removed before choosing a new VP (who can be literally anyone in the country who is eligible).
In this hypothetical scenario, I was describing what would happen if both Biden and Harris were to be removed from office. And then I also was describing what would happen if the whole line of succession died at once.
