I've decided that the sad people were Schrodinger's sad people they were neither dead nor alive until someone saw them dead. Harvey was dead because Bobby found him dead. Bobby, who wouldn't have been released from the first house until Sam and Dean went to take care of THAT Soul Eater many years later, wasn't found dead by anyone, so he was alive, even though that Soul Eater wasn't killed until like 20 years later. Frankly it makes my head hurt and a local wine shop is having wine tasting tonight, so I'm going to go try lots of wine and not think about it too much.

I'm sure this was foreshadowing a lot, but I'm not sure what. I mean other than being beaten over the head with "not everyone gets out alive" and "there is always a sacrifice". But who won't get out alive and who will be the sacrifice, I have no idea.
