It's awful when your brain has something to beat you up about. I found it much harder when Molls died, because I was stuck in that 'what if' place and thinking I should have chosen for her to have an operation (of course if I'd done that and she'd died, no doubt I'd have beaten myself up about that instead, because my brain is more abusive than logical, apparently.)

But with Az, he was so very tired, but also content, with nothing left to worry him except that his body was letting him down - if he *is* hanging around as a ghost now, I'm pretty sure it's a happy ghost.
