What is the required waiting period (*turbus*) for a male slave whose wife is missing?

Primary text

If the missing husband is an enslaved male, and his wife is a free woman, her waiting period is the same as that of a free woman married to a free man. If his wife is an enslaved woman, her waiting period is the same as that of an enslaved woman married to a free man. This is because the waiting period is considered relative to the woman, not the man, as is the waiting period established due to absence.
