Divorce and your conditional residence status
The problem here is that it seems that your friend never even received the conditional residency.
If your friend did receive the conditional residency,
Then a appeal to remove that conditional residency,
Must be filed before the end of the conditional residency card.
If a divorce occurs, then it must be attend with the divorce waiver.
It is possible to get the permanent tenancy,
Under these situations if everything is properly done.
