I doubt Sinestro knows fully. If there's one GL he hates close to Hal level, I think it would be Kyle. That's just me though. Also, I don't think Sora's getting fridged anytime soon, cause she's too good of a character. I love the whole Medic Lantern aspect to her. Also I don't think Jade is going to cause any Kyle Sora friction. That issue seemed to already be resolved in another comic.
Well we've already seen what has become of poor Sayd. Also, in regards to Sinestro, I don't think this is his redemption at all. Like you said, his personality is still the same, and I think so are his beliefs. He truly believes fear to be a more effective way to bring order to the universe, cause he proved that it worked in his sector. In regards to Abin Sur, I don't think we're done with his story yet due to the Indigo Tribe. They are still a mystery in all of this, and Abin Sur is tied to them somehow.
I think Sinestro just doesn't care. But time will tell. He doesn't seem to HATE Kyle as much, but yeah, has quite alot of friction there. And generally enjoys being cruel to everyone and tearing up Ferris Air property. =P And we've already seen SOME amount of friction in Brightest Day so far. We'll just have to bide our time to see if it follows.
And Sayd? Look at Ganthet in GLC. Dude looks like Midget Hercules. Fulla manliness, making his own ring manually. Being AWESOME generally. You think he's gonna let anything bad happen to his woman? =P And although Sinestro has his beliefs, you see how Secret Origin and the whole Blackest Night arc have been trying to humanize him? I'm not saying his acts are justified or that his attitude will change, BY FAR, but heck, I'm all for his ideals regarding not letting the stuck-up Guardians decree how the universe should be ran. Arin Sur as a lover served to make people see him as someone with feelings, with a justified hatred of injustice. And being the first White Lantern, fulfilling his mission, not for himself, but for Abin Sur, made me respect him alot. I'm guessing people are gonna start looking at him differently, no matter how much of an ass he still might be. =P
And yeah, you're right about the Indigo Tribe and Abin Sur. I kinda forgot about that for a moment. Geoff said in today's interview that we can expect to see them and William Hand as a new recruit later this year. So far, they seem friendly. So maybe they'll help after the Predator mess is taken care of. Let's get ready for the 90's-influenced beast that's gonna be the Star Sapphire's very own villainous entity, in his comic with a cover full of bondage. =P
inb4 marvel version
Marvel HAS announced its version. And then cancelled it. And then replaced it with that chibi-looking mini superheroes MMO thing. Sucks to be awaiting that right now.
