Okay, I've made a quick desicion.  I'm not staying up to reasearch Enca circa WW XII, because like my subject 

 it's around 2 AM where I am and I'm falling asleep.  So, for the time being:
+ + SPAWN
Because I find her earlier behavior suspicious and un-innocent-Spawn-like, and so far she has done nothing to alleviate my concerns.
My other suspects are kind of getting all muddled together in my head.  I must need sleep.
