The moment it was mentioned that a barrier stone was in her home forest, and that she passed it many times, I instantly thought that maybe that's why she was different to all the other slimes. I mean, clearly there are other such situations regarding slimes possessing dead bodies before Jelly. However, the fact that only specific rare slimes tend to develop such desires makes me wonder if they do so because of their proximity to certain nodes of power. In Jelly's case, it was the barrier stone filled with divine power.
Some food for thought.
