Battlestar Galactica
Tigh Me Up, Tigh Me Down (2004-12-06)

Suspecting that Commander Adama may be a Cylon agent, President Roslin tells Dr. Baltar that Adama should be the first person to undergo the now-functioning “Cylon Detector” blood test, a process that takes eleven hours to complete.

A lone Cylon Raider appears when Adama is suspiciously off-ship. A combat air patrol disarms it, but Col. Tigh deploys a Raptor to gather data on the enemy. Shortly after, Adama appears with Tigh’s estranged wife, Ellen, who everyone thought had died in the initial Cylon attacks. Adama is suspicious of her sudden appearance and orders Dr. Baltar to put her blood test ahead of anyone else’s.

The plot on the Cylon Raider is superfluous as it just goes nowhere and the ship is destroyed. Tigh may be No 2 in command, but appears to lack discipline for the purpose of the story. His drunk wife just gets annoying. What they do with her in the future will be interesting as Tigh may resort to drinking again.
