Cohort and followers serve the leader. They willingly put their lives in his hands, because they see something in him, they believe in him. They are loyal towards him. But what attitude could followers have towards each other? I'm talking here about those followers that do actually work together or at least know each other (I know that a character could possibly nab himself followers from two rivaling organizations or races and they would obviously not like each other). Are they likely to be friends?
What about cohorts/followers by proxy? How could they feel about the leader of their leader?
Assuming the cohort shares at least some (and preferably many) aspects with the person they're all following (for example the same alignment, organization, religion, outlook/opinions, skills, abilities or background), what attitude could followers of his leader have towards him? He's basically something like a lieutenant. Would that make them at least on friendly terms with him, if not also loyal and subservient?
If the leader is a PC, what could his cohort and followers feel about the other PCs?
More mechanical question - how reasonable would it be if I gave Leadership to the cohort and allow him and his leader to basically "share" the same followers? I'm asking because there are some feats and abilities that give benefits to followers. Not too many, but there are. So instead of using up feats of the main guy, his cohort would be the designated "inspiration provider".
