Cool quote from Sabina in The Unbearable Lightness of Being: (not word for word cos I can't remember)
She had betrayed x, y and z. If there was no one else left, what was there left to betray? Was this unbearable lightness of being the ultimate goal of her betrayals?

Because by betraying she was actually freeing herself form the burden of love. I can't remember who's x, y and z though I'm sure one of them is Franz and maybe the other is Tomas...?

Okay so cool that it came floating into my head suddenly while I was reading a case (Heron II). ._. Needs to concentrate...
