Oh, dear! That was truly an unexpected development...which, of course, is the hallmark of any well-planned story. Brilliant plot-twists, like the one in the previous chapter!!

More specifically; the Golden Age GL was never powerless against yellow (the band of the emotional spectrum representing fear). Just wood! Ergo; Jade was able to overcome the fear-based power of Despotellis' ring-enhanced germs.

But, with her emerald energy being magic-based, will she be able to overcome a Mr. Mind-controlled Zatanna? Only time, and the next suspenseful chapter, will tell.
