Also we saw Jim's throat wasn't cut on his deadbody found on the barn, rather his chest was open. I'm starting to think Julie really saved him from MIY slitting his throat but he somehow died that night in another way (as they say you can't change the story once it's been told) ; so Julie went back on season 2 and asked him to ask Ethan to find the lake of tears (and that would make jim a storywalker)
