So Supernatural (episode Death Takes a Holiday) just killed off another friend/cohort of Sam and Dean Winchester. I’m sure Bobby will be dead by the end of the season.
You’d think the psychic would have wanted nothing to do with them after the angel Castiel blew her eyes out. (And why couldn’t Castiel have protected her as payback for blinding her?).
But no, like the good-hearted, anonymous Star Trek ensign, Winchester pals just can’t get enough. Until they’re dead.
An expendable ensign on Supernatural. Die ensign, die!:

I don’t doubt that they’d kill Bobby off. But, since he was brought on to replace their dad, who then will be the brothers’ older mentor? Maybe they’ll bring back the lady who owned the bar from season 2…until she dies next year. After that, who knows?
