This is all related to another post I have yet to finish - let's call it a younger sister - which has to do with the inevitable killing off of my favorite characters. It's usually completely unnecessary and hardly anyone does it right; but I'll leave that complaint for the other post, a little thing that grew so big that I just decided to wait for season finales. I started it back in January because of Medium, then got sidetracked with other examples, life, and then more chararacters leaving. So BOLO for that one...or not; whatever you wanna do. I'm not forcing you. If only I could.
Here is a great interview with John Noble about the finale of Fringe and season 4.
