Hey Ahoapap
sounds like the player should perhaps be playing another playbook...
if you REALLY don't want followers, don't play a Hocus...
Here are some suggestions for you...
*Check out the Hocus PB, under followers suggest the player take the option
"your followers aren't really yours, more like you're theirs."
this may work well for this player...
? Questions for you to ask... position like this perhaps;
ask the player what the character does, what they believe in...then spring board of the answers. for example. I don't have a cult, I help the community... oh, how? I help organize food and do some work... ok, so you help out Tinder and Jex...they and the others have really taken a liking to you and appreciate your help they seems really interested in what you say when you work with them... Mission also works there with you, but do you trust him? why/why not - was it because of the time he/she ...... get the idea?
Ask the players questions, don't be afraid to make shit up, or use other NPC's that you've made up already or other players have introduced to get some triangles going also. Just because one player has a bunch of peeps in his crew doesn't mean 1 of them cant be a follower of the other pc!
As for the 10 people you have in triangles... good to keep track sure, but don't kill yourself on it - I update a "people and places of the apocalypse" after every game, takes a few mins, but perfect to add little notes on the npcs/pcs. Like Rolfball the Merc. is in Jax's Crew, but he's got the hots big-time for Jaeda! You can do the same on a scrap paper with the npc's and pc's names draw lines and make a note or two as per the relations.
Have fun, hope that helps
