I found this picture of what might be the death in Episode 100:

There are other screenshots from the episode there as well:

Well, everyone thinks it's going to be Lana and then Jonathan....after some type of reversal. I don't know what to think considering it's tv land and a picture only says so many words. Not ruling it out, but you never know. It'd be the most logical, but what if no pictures or information of the real death were revealed? Chloe's not even mentioned in this episode, is she? ...Maybe there's a reason for that. haha I don't know. Either way, we'll find out in a week.

I'd rather wait and find out when the episode is aired anyway. Knowing ahead
of time would ruin it for me. That's why they're called "spoilers," I guess (duh!).
