It’s been four days since 9-1-1 did the unthinkable, unapologetically killing off Peter Krause’s Bobby Nash, and fans are still riding out the waves of devastation. And — not to make things worse — but, if the cast’s reactions are any indication, it seems like those heavy emotions might linger for quite a bit longer.
