Sadly, because I like both Kylie & Paula, I think the ptb probably rejoiced when Paula announced she had agreed to leave (I did read somewhere it was a mutual decision) as it was a perfect opportunity to sort out the mess they'd left themselves in by making Kylie a killer!!
Sacrificing the character to save the Platt family as a whole has sadly become the most realistic course of action so no I don't see anything but a tragic death for Kylie, which will at least give Paula a great send off & people will remember Kylie with affection & sympathy rather than as a killer who got away with it!!
