What happens with a student that is inherited from another CFI who is no longer around?

The rule is the same for each 90-day solo re-endorsement. The original certificate endorsement continues to be valid, but new CFI has to "provide the training" in order to sign the new logbook endorsement.

Don't read too much into "provides the training." It doesn't say "provides the =initial= training." Go through the required tasks and knowledge areas to satisfy yourself that the student can perform them to your solo standards. A mini-checkride should suffice.
