Wait, really? As in they or others like them aren't coming back in future episodes? I have a hard time believing Nomura would abandon a fanfiction-caliber deus ex machina like that after it's been introduced, but this does give me a sliver of hope for the rest of the remake if true.
The final boss in the remake is The Whisper Harbinger which by destroying it gets rid of all the other whispers. So while death now has real consequences (no more stuff like Barret surviving), there's also the notion that they're not there to keep the original story from happening the way it should so anything can happen now. Although the writers have said the story will still be pretty damn close to the original so I won't let myself get too worked up about speculation at this point. ---
