"Buried" = Pure invention by some Kyle fans/Johns haters.
Johns treated Kyle with nothing but respect. The whole time though some Kyle fans were yelling -
but he used to be special! He was the ONLY green Lantern ... Why isn't HE SPECIAL ANYMORE! And DC kowtowed to this at every turn, we got Kyle's continuing Scrappy-Doo adventures, as Magical-Ion Center of the universe, and then again as Mary-Sue-Rainbow-Lantern specialist Lantern of all!
They even ripped pages from John Stewart's Mosaic book, where
he was once the artistic outside the box thinking GL, prophaside and chosen personally by the Guardians, to take the power to the next level. All that was scraped and given to Kyle instead.
If anyone should complain, it's John fans, who had to watch their character get crippled so Kyle could get the only ring, and then when they realized that wouldn't actually stop John from being a Green Lantern whose power runs on the will of the mind, not the physique, they crippled Johns brain too! (as they had done to Jordan), all to justify Kyle as the only GL.
Kyle fans have no business talking about "put a knife in his back and clearing the way" when Kyle's whole character and concept was built, and sustained, on the broken backs and minds of other Lanterns. LOL!
The ones complaining about the Corps and r Earth's origianl Corps Lanterns coming back to prominence, were largely Kyle fans.
Yes it's true, from one end of the spectrum to the other.
Again; Green Lantern built around the unique Corps concept, which implicitly allowed for
multiple characters to share and/or swap the power and title, allows for it.
It's for better and worse able buildup to a multi-character, and book, franchise. With that, comes the favoritism.
