WOTG, quick suggestions.
Deception is Iblis' strength. Have him deceive the Cylons with a projected lie so they of their own volition chase off on the wrong vector.
Lucifer or some Cylon IL should be immune to the deception, so he continues a cautious pursuit.
The pursuing basestar is out of contact with the Cylon fleet. It is alone.
Adama notices this subsequently after WOTG and turns to fight.
Have Adama play a cautious cat-and-mouse game with Iblis. Use this interaction to educate Apollo to Iblis true purpose?
Sheba is susceptible because she lost her father?
SoL and BoL provide passive assistance. The Galacticans must face down Iblis using their own goodness.
Earth should remain unanswered.
As always;
