To be honest I don't think you will need it, Jenna, Carl and Leo has 2 routes and they are easy to made (only one choice that define route)
Nevertheless if you want to know I will write it down so if you don't want to read it don't click "View rest"
Jenna route: We kept each other sane/ This town break people (this one is actually tricky cause this choice is in the middle of a game)
Leo: the very last choice ( that's easy )
Carl: Fight it/ Let it help us (that's in the middle of the game too, but this one is kinda obvious to my mind)
Hope I helped :)
