Like others said he only became interesting at the end, when he had his eyes opened so to speak, and stepped up to the occasion. I did think it kind of strange that he developed into a leader. Not to disparage the character, but it seemed like he was just a simple freighter crewman/lackey when he was under Dukat, and not particularly clever or charismatic. Dukat seemed to just reward him with power due to his loyalty. You would think the Dominion would just kill him after Dukat stayed behind, and put someone else in as leader. You know, someone like one of Dukat's enemies? Someone with leadership experience but who is also controllable?
Not someone inclined to help a liability like Dukat. Not someone who is going to maybe resent the situation and start a rebellion XD
Also he liked his sauce. I wonder what they used for canar (kanar?) It looks like maple syrup.
