What a difficult question to answer for multiple reasons. The story did not reveal much in terms of what Rita and her family did to help Inez. The girls went home after burying George, and spent time with their parents. Rita genuinely thought that revealing her engagement to the Count would be well-received by Inez & lift her spirits a bit. Staying in her room, sitting outside on the bench, and going to NYC alone were actions consistent with mourning. George’s death was tragic, shocking, and brought about intentionally. Of course, the entire family, but especially Inez, would be deeply impacted. But suicidal ideation? No evidence of that was revealed and, again, viewing the situation in the context of knowledge available at the time, it’s hard to say anyone should have seen warning signs or expected Inez to take her own life. And even when family or friends suspect someone is planning to do so, they are often powerless to stop them. If someone really wants to end their life, they will find a way to do so.
