The most epic battle in BLACKEST NIGHT yet comes to a shocking conclusion as Hal Jordan makes the ultimate move to take on the Black Lantern Spectre. But what price comes with the unleashing of Parallax? And what does this mean for the future of the emotional spectrum's avatars? 

If Hal can exert control over Parallax, that should mean he can bust Black Lanterns all by himself now since he can deploy both Will and Fear in combination, right? Where does that leave Sinestro? Could Hal just turn off all the Yellow rings once he's done (again assuming he can control Parallax)? 
 
Also, have any of the other emotion avatars (platonic ideals?) besides Parallax, Ion, and the Predator been revealed? We know Predator is loose and I think Ion is currently hostless. Perhaps all seven of them can be bound in one body.

I'm sure he'll be fine lol. Probably become the White Lantern.

what if he becomes part of the spectrum like barry did with the speed force way back when

With Hal having been previously corrupted by Parallax and subsequently overcoming that, I don't think he'll be able to do the same thing.  There will be a price, certainly.  Whether it comes in the form of his will being diluted by fear, or some other manner it will be interesting.  You simply can't turn Parallax off like a switch.  Hopefully, Geoff Johns adds some real depth to this quandary and not just a happy go lucky ending to it.

What Price Will Hal Jordan Pay For Parallax In GL #51?       About $4 too much.   "

I hope that Sinestro gains Parallax in the future, that would kick so much ass.

" Is the end of Blackest Night gonna run right into Brighest Day, because waiting a year for something that doesn't seem like it gonna be a bad for anyone is just lame.  we know the White Lanterns are coming but when does Brightest Day start?????? "

Why? Why couldn't Sinestro absorb Parallax? Ah well, I just hope Hal doesn't die again, he's the best Earth Green Lantern.

" Why? Why couldn't Sinestro absorb Parallax?

Batman could kick Parallax's butt.

Written by GEOFF JOHNS • Art by DOUG MAHNKE & CHRISTIAN ALAMY
Cover by SHANE DAVIS & SANDRA HOPE
BRIGHTEST DAY shines its light on the “New Guardians” who have been forced to make Earth their new home! Why? You’ll have to read it to believe it. While Hal is forced to deal with Larfleeze and his newfound appreciation for Earth culture, Sinestro uncovers the mystery behind Parallax’s disappearance.

No, Sinestro controls the rings (as we saw with Mongul). It's the Sinestro Corps for a reason.  The only other avatar that has been revealed is the orange one, but the reveal was just that it lives in Agent Orange's power battery. They really need to bring these into the fold. "
