The secret probably won't make any sense to me anyway.
I think 'nek' means Green, 'rot' means Yellow, 'lek' means Ring, and 'rok' means Lantern. I'll need a bit more than this to seriously come up with a translation of this gibberish though. Sorry, 'language'.
I think he meant that literally. You know, working for Ferris Aircraft. Not, you know, working for her as her sex slave man servant. Although that might be what she meant.
Hal and Sinestro have a minor tussle (really minor since Hal's ring can't hurt Sinestro) and Sinestro reveals to Hal the second reason he's come to Earth seeking Hal's help.
Great! I hate plots that are driven by glimpses of the future. Laziest way to get a story started ever.
Another Power Ring that spares the fabric when creating a suit for a female wearer.
Hal Jordan wakes up in a cell with a dead ring. Again. Black Hand approaches him and tells him that Sinestro will be saved as he was. Abin Sur is also mentioned again. I have no idea who Black Hand is or why he's important. He was part of the Blackest Night and he was a bad guy and he was some link or something to Necro the Black Lantern Leader (?) but then he was taken by the Indigo Tribe and made into one of their own. But maybe it's different in the reboot! Right? The New 52 and all that?! Right!
Anyway, that's the end. No secret of the Indigo Tribe was ever revealed. It probably has something to do with Abin Sur since they keep mentioning him.
Green Lantern Issue #7 Rating: No change. I doubt the comic will change much in its reliance on past Green Lantern history since Geoff Johns has been writing it for nearly a decade (I think). So he's going to continue to include lots and lots of things from past story lines of the old DCU because he's a writer and that's what writers do! They build on their material and then they feel like geniuses when they can incorporate some obscure thing that was barely mentioned 55 issues ago into some critically important part of a new cosmic threat that will end all existence. Yay.
