SGA and how not to defeat a villain

Season three continues to be pretty great.... except it has this weird hangup with Lucius, the creepy sitcom roofie guy, who reappears, getting a whole second episode dedicated to his "hijinks." Being less revolting, I did watch this outing all the way through and was "rewarded" by this being the episode which wraps up the ferocious feud between Sheppard and this show's most effective recurring human villain.

Concluding a multi-episode high stakes arc with an episode in which he felt like an afterthought.

It was a lot like if Xavier St. Cloud showed up and was beheaded during 'The Ransom of Richard Redstone.'

Or if Buffy staked Drusilla during the last three minutes of 'Go Fish.'

It's just fundamentally unsatisfying to me.
