Caroline dying in 8x05?
The synopsis states "Stefan and Others" suspiciously, that, along with Caroline helping Bonnie with Enzo (keeping her in the synopsis throws us off) plus "advice" sounds like she'll give Bonnie some grand speech about love, and that will be her final speech.
I don't think maybe Damon kills her, it's just too much for Damon to kill Caroline and still be saved by ANY of the group, even Stefan, I think Tyler dying could be a red herring. Plus, this could explain the early engagement.
It'd be a welcome bold move by the show IMO, if you're going for shock, go for it, Tyler isn't shock but dissapointment because he's hasn't been here, Caroline has, and she's THEE most connected to the group atm, to Stefan, Bonnie, Alaric, and Tyler and Matt both love her. She's honestly the most affective death this show can have right now.
What does YOU think killing Caroline off could/would do to the show, is it what you want? Who do you actually think is dying in Ep 5?
