He's just being a tool.
Sucks that happened. Only thing you can really do is try reloading the game. If that doesn't work, you don't have much choice but to start a new game. There are many bugs that seem to come out of nowhere with this game. Very random.
Just had a bug today that allowed me to ride horseback from Tommy's hydroelectric plant all the way to the ranch without a single hunter showing up (the scene of the horse jumping the log and a molotov igniting did not happen). After exploring for awhile, I had to reload and it happened again. I had to quit all the way out of the game to get it to work right again. I've had this game about eight months and have played through every mode (finishing up Grounded+ now).
Tomorrow is pretty much my last day with PS3 version of TLOU. Watchdogs will hold me over until TLOU:Remastered comes out. Here's hoping the massive amount of bugs are fixed.
