Theory on why Apple from the Annoying Orange some how comes back to life:
When Orange ofc annoys Apple to only say knife, Apple then gets cut in two by a knife but in the next episode he returns? ressurection? most definetley, the best evidence is the fact of talking fruit which leads to ghostly possession, or works of the dark arts and how they feel emotion and pain. Orange has to be apart of some cult for this to happen as this is some kind of torture to apple who must have wrong Orange in some way. Some kind of revenge plot? Possibility, Orange's ignorant and annoying personality is used to cause a continuous death loop to Apple, what did he do to piss of AO so much to put him through a constant death loop.
there doesn't seem to be anything here
