There isnt one. It goes from her death at the end of season 3 to her funeral at the start of season 4.

There is one, but they decided not to publish it.

Go to a movie shop and buy the dvd-box. Have you ever stopped to think about that?

i dont know but it doesnt show it i dont think

I also search it, but I don't think, that someone can find it. I mean, they decidet not to publish it, so I don't think, that we have a chance to find it.
