You just learn to ignore the horrible religion-heavy episodes ("The Reckoning" had unintentional comical value, though)
The Reckoning is a beautiful episode that teaches us that Force Lightening comes in two different colours.
From this angle it looks lkike they are both shooting from the hip. The wormhole aliens can be naughty when they set up their confrontations.
