It never really gelled with me. Even the writers admitted it was only done because they were the two most prominent black characters at Marvel.
It is nice to see John move past his guilt for Katma and Xanshi. Though, when you think about it, is Fatality's love for John real? She's been brainwashed into it by the Star Sapphire, after all.
On the subject of John, I have to make one minor quibble in regards to Green Lantern #20. In the epilogue, John is called Guy's greatest friend. That's just not true. Guy and Kyle are the ones with the bromance, not Guy and John.
