Johns added "Abin Sur was my teacher" to Sinestro's background, which worked. Now he's adding "Sinestro was in love with Abin Sur's sister and her death drove him crazy" as well? I have my reservations about that. Sinestro thinking "So what if I blur the line between control and fascism in order to keep the peace on Korugar" is more creative than
"Chaos on Korugar and love interest getting fridged make Sinestro something something." "Go crazy? "DON'T MIND IF I DO!!!"
Will Arin Sur be revealed as Soranik Natu's mother? Because *that* would be cool.
