Change the text of leadership to the following:
Benefits: This feat enables you to attract a loyal cohort and a number of devoted subordinates who assist you. A cohort is a PC with class levels (created and played by the player), while followers are typically lower level NPCs. See Table: Leadership for what level of cohort and how many followers you can recruit.
Cohorts begin play with all the amenities of a PC of their level including point buy, gestalt levels, character wealth, traits and immunity to the diplomacy skill. For all intents and purposes it is a second player character.
