I have a theory on the season finale for the show. But first, how are the toys alive? Nobody knows. Whatever substance or entity that may be, let's pretend it's some force that keeps them going.
Now, in the flash forward seen in Descent leads us to believe that the toys "die." So let's pretend they do.
After their death (presumably occuring in the last episode), I am guessing now that Jon finds out his Arbiter and Chief toys have somehow been broken, he replaces them with newer, quality Arbiter and Chief toys. Once he brings them home, the force that was once in the original Arby and Chief moves into the new toys, bringing them to life to question their existence once again and live their lives as new toys, which would end the show on a good note, leave questions answered and not have to bring more adventuers for the toys. Eh?
It's a foggy theory, with details left out, but what do you guys think? Stupid? Possible? I'd like feedback (:
