I'm growing more and more convinced that...
... it is highly plausible that Rayna will die at some point in this season. This obsessed creep storyline will certainly not end well, and honestly, I wouldn't complain if she does die, I see it happening, and how it has been playing out so far gives me very shady dark vibes.
Don't get me wrong, I like her and I don't particularly want her to die, but after all this is the final season, so it's not like her living will extend the course of the series, and I'm definitely in for some shock value. Having Rayna -the leading actress- die will leave a mark on the series, and will probably garnish great critics and draw a lot of attention. After all, the TV series where the lead dies are very limited.
I feel like she might still appear for the remainder in flashbacks or dream sequences.
Anyway, looking forward to see how it plays out...
