I think however, it was more to do with them not wanting to be predictable, for whatever reason. The others things, I'm not sure on those. I heard from one of the 'did you know' threads it was supposed to be between saving Luke and Kenny in the storm and Jane might've drowned in the lake of stupid instead. But the early episodes did seem to set up the whole 'these two will be important to the main story' something that greatly interested me because of how vastly different they were and it opened a lot of debates to me on which was better equiped to deal with a ZA and who was Clem better to be learning from etc etc. And I like Jane, I would've prefer her to come back for another season not as a determinant character, but if she'd been the one to die in the water saving Clem, it might've redeemed her character after being a loner and trying to be distant from everybody, so it might've worked...with it not being a lake of course.
