RE: Young Justice
So Wally West "ceases" to exist in yet another DC universe? This character just can't get a break.
RE: Green Lantern
After seeing Aya's origin story a few weeks ago and then her fate in the finale, I wonder if the show's creators intended Aya to eventually become the Emerald Eye (from the Legion stories of the 30th century). During the origin episode in particular, Aya's appearance and power level seemed to vaguely suggest the Emerald Eye (to me, at least) and her name is phonetically similar enough for not too great a leap from Aya to Eye.
Or maybe I'm just seeing portents and connections where there aren't any.
