DC writer's don't communicate with each other
Hey, look it's Kyle! Wait... isn't he Parylax? Well, not in this issue of Countdown.... Just like John Stewart & Hal Jordan aren't fighting in the war in JLA & JSA..... There is no continuity within DC anymore. There's only 52 earths right now, and their storylines have all been used up.
However, this was a great issue, aside from those major errors. The Piper and Trickster stuff is a lot of fun, makes me wish they had their own series.
I understand a lot of people hate this comic, but it really just is good natured fun, nothing more... And it supposedly leads up to Final Crisis, the last of all crisis books, at least we hope so.
