Talk, talk and talk, because in the end we all know that Danzo will "mysteriously" escape. Don't stuff the words, go straight to the end and end with this stupid mini-arc that results in nothing more than him being exiled from Konoha.
So he’s going to leave the village? Because I think it would be more interesting is after he kills danzo they outright tell him as long as he does nothing else he’s welcome to remain a member of Kohona.
