I just never paid enough attention to non-Aspenite elements of the IC after the Vagrant joined up with the convoy, I didn't have enough time to read it all, so I didn't even realize Cain was talking to himself or Richard.
From the little I have read since then, I have got that Foley was infected, Glenwood got buttfucked by the Vultures, the caravan decided to hole up in an office building while Jen and Cain were captured, Paulson went batshit crazy, the Vagrant's friends/brothers/
Is this all correct?
