Hollywood's golden rule: No one important dies off-screen. In a book those would all be POV characters. My guess is if they die during the series, they will be given a "good" death, not the Middle-Earth equivalent of falling from a cliff while taking a selfie.
Plus Bronwyn just escaped what looked like certain death via orcish acupuncture, a wound that would have spelled the end of any character not wearing a name tag.
