I think that Grubbage was a kind of grayish-white character. Triss never documents anything that Grubbage did tht was bad. He was just this kinda stupid deaf rat. It was only Plugg and his crew that got him into the bad guys. Malbun says that Grubbage is "not at all unlikeable", and that he is an excellent nav.
