I'm really sorry, that I've forgotten to answer you post, Myrkin

I'm developing the theories (or rather the similarities) and establish a discussion and then, I forget to reply

"Live together, die alone" figures in Lost as well as in Watership Down.
It does? When was it said in Watership Down?
Maybe, it wasn't really said (but I think, I've read something like that in the book). But, in the tv-series, this behavior can be seen. When Holly is calling for Bigwig, he thinks, it's the Black Rabbit. He wants to face him alone, because he thinks, the BR would take also the others, when they face it. Campion also wants to stay away from Blackberry, because he was touched by the BR (ok, not exactely the same, but I hope, you understand, what I mean).
I think it would be a good thing to elaborate on those points (or at least on some of them), because in this current form similarities between characters seems to be only skin deep.
To be honest, these similarities are really only superficial. I watched Lost with the thought at the back of my mind, that Lost has similarities to Watership Down. Then, I've seen the characters and had to thought about the characters in Watership Down. And I needed to write it down (before I forget it

).
