Brian Markenson is Lotan, a "wobot" that looks like an Enkaran.
He's also the computer on a huge spaceship that is gonna terraform the planet SG-1 deposited the Enkarans on. This planet was mentioned in "Watergate"...
But he's also an Enkaran, the computer did too good of a job creating this guy. So he's got feelings about the Enkarans.
But he's also got that pesky programming that requires him to melt the surface of the Enkarans new planet into Slag... What to do? What to do?
It's actually Jackson that figures a way out of the conundrum. With Lotan's help...
It's the ending of this that is great... the episode itself is rather depressing. I usually start watching this halfway through... the ending always lifts me up.
Look for Mr Gaeta from BSG, Allesandro Juliani. We had Chief Tyrol as one of Bratac's students in the episode where we met Oma, and he was very young as Gaeta is here.
When Jack wants to use Naqueda bombs, Daniel uses Diplomacy. Which works better. Sometimes, ya gotta use Naqueda bombs though...
