No worries! The PCs met the hitchhiker, and very cleverly deduced the backstory and his "weaknesses" without me having to directly tell them. I have the Feb 25th version of the preview doc but opted to go primarily off of the Quickstart Guide for this. We briefly looked over the doc post-session. Players particularly liked the changes to the Scars, which have more narrative consequences and is reduced to a single roll. The next time we play, I am going to run The Will of the Forest by M. Allen Hall (which I picked up at PAX Unplugged). If the players like, we will use the rules in the doc going forward. Thanks for the great game!
