Lights Out is doing exactly what it set out to do, cause some big crazy changes while telling a fascinating story in the Green Lantern comics.
Hopefully you've been reading because we've already seen some pretty big stuff happen. The third chapter is in GREEN LANTERN: NEW GUARDIANS #24, on sale this week. We talked to artist Brad Walker about the issue.

COMIC VINE: Did you get to see the scripts to GL #24 and GLC #24 in order to fully pick up the tone set in the arc?
BRAD WALKER: Hmmm... I can't remember. I may have been given them, but I don't remember if I read them. I'm gonna chalk it up to time constraints. I got the gist, though!

CV: How crazy do things get in NEW GUARDIANS #24?
BW: They definitely get weird. I got to do some fun design work and creature drawing. But I can't elaborate, more than that. A LOT of characters in my issue, though. A LOT.
CV: Is it strange drawing the middle part of a story arc?
BW: Nah. That's par for the course. I've probably drawn more middles of stories than beginnings or ends. Going back to my first work in comics, on Batman crossovers, 10 years ago.

CV: Does anything make Kyle Rayner stand out to you compared to other Lanterns?
BW: Well, being the only White Lantern is unique, in and of itself. He's the only character that can wield the full, emotional spectrum. And he also doesn't come from a heroic place before becoming a GL, like a test pilot, or a marine, or something. He was an artist, and a struggling one at that, which I think gives him an angle of sensitivity, and introspection. That gives him a unique approach, especially considering it's a concept that's based around emotion.
CV: Are there any happy moments in this issue?
BW: Hmmmm....happy... Is there a ring for happiness? I don't think there is. I guess we don't get to have happy.

Be sure to pick up GREEN LANTERN: NEW GUARDIANS #24 this week to see what happens next in Lights Out.
