When I heard Dimma I was a bit surprised by his apparent candidness. But on reflection I think it was just feeding the chooks Keating-style.
He didn't actually say anything.
He might go if or when we rebuild. Might. But right now we are regenerating. If things keep going well, we could be regenerating for the next 10 or 20 years! He also said rebuilds are bad n'kay. If they don't keep going well and we are forced into a rebuild, he might leave, he might stay, if he leaves it will be after 15-odd years and 3 flags, nothing lasts forever.
On Dusty, he has my blessing. What else can he say? If he leaves its a betrayal? He's already said he owes us nothing, which is the same as he has my blessing. If you love someone set them free man, especially after a couple of cones.
