David has given me an interesting puzzle. What about the use of magic which works, but is specifically mis-aimed? Also, what about using spells to divert the spell energy to another effect?
If you call on the evil force which is imprisoning A to stop its attack, and free A....except B (your presumed evil force) is not evil, and is not doing the attack, but A is doing the attack.....if after this you bind the attacking force from word or deed....
At this point, I think you've freed A, stopped A's attack, and bound A up again in a new spell.
Of course, A is an archmage, and uses the spell's energy to create a few loopholes in her new confinement.
Later David tries to get A to accept redemption which I wasn't sure was possible since A is Queen of the Vampires....but vampires are not always irredeemable in every world.
And oh, yes, although it didn't get developed we had a supernatural hostage crisis...
Hostage: David's dop--a ghost
Location: Cave in Iraq
Hostage-taker: Lilith, queen of the dead.
Cops encircling place: Archangels
Controlling commander back at HQ: David
The whole idea of a supernatural hostage-taking has some potential, but it didn't get developed. It just sort of happened too...not really my plan exactly although it was the logical end result.
