This just tells me, that there are specific characters being kept alive for no reason. Their decisions make no sense within the context they find themselves as well as based on their previous decisions. It's almost as though someone else wrote their character compared to the first season.
Bare in mind, this is about one specific character not a generalization.
It boggles my mind, that this character is more aware of the dangers than anyone else and doesn't say anything to THE RIGHT PEOPLE. Instead this knowledge is used to just reiterate on their background which already been established and fleshed out. This is the route towards dead writing, I hope this was merely a mistake and is not something to expect going forward in the show.
Dead end characters should be killed off or become a supporting character.
