Welcome back for the second part of my annotations of “The Lightning Saga,” the five-part storyline currently unfolding in DC’s Justice League of America and Justice Society of America titles. Writers Brad Meltzer and Geoff Johns have revived the tradition of JLA/JSA teamups, once a staple of the original JLA series. That’s not all they’ve brought back either, as some semi-obscure references keep popping up in the script and plot. I broke down the first chapter from JLA #8 here, and now it’s time to turn our attention to the second episode, in JSA #5. Hopefully, this will be of assistance to newer readers, unfamiliar with the nostalgia-inducing source material.
