Kate's Six Feet Under Fifth Season Predictions

I love Six Feet Under, but I can't help thinking that the story lines in the final season are heading for obvious conclusions.

In this season, we will see:

• The simultaneous births of Nate and Brenda's child and Keith and David's whatever in the last episode.
• Long-suffering Ruth divorce George and discover that the joys of grandmotherhood fulfill her life.
• Claire leave Billy (after barely escaping with her life after an insane outburst) and leave Los Angeles to find herself.
• David--rather than Nate--give up the funeral business, for the sheer irony of role-reversal of the brothers.
• Rico and Vanessa will get back together after a few more instances of being supportive of each other's separate dating lives.
• The dead father make a final appearance, but will not resurface ever again because his wife and children have resolved all their issues in the difficult years after his death.

But I can't decide if a main character will die. Main-character deaths are oh-so-overdone but is probably expected from a series about death. So from that perspective, all the Fischers should survive. Or should they?
