Really I loved Vowrawn and his humor, he played the political games which I love. I also really liked Darth Gravus and how he didnt even bat and eye lash when Thana walked out on him, like he had seen that before and was going to see it again.
I hated Thana. Gravus was cool. But Vowrawn's humor just became annoying after he got out from that death field when Draahg fell on Corellia. Made me want to put him back in the death field.
Best was when he mocked Baras though. I laughed when Darth Cartman called him a "fop"
