SPOILER!!!!!!!!!! At the end of GL 51, after Parallax has left Hal's body, Hector Hammond cries out"It has Parallax!"  
 
Who do you think the "it" is. I have one theory that the "It" is actually Hammond, and
 he will n ow be a mobile threat.  
 
Another theory is that someone unheard of is collection all the emotional entities.

Guy also has a Green Ring AND a Red ring.

Anyone else have any theories? all opinions are welcome.

I don't know what "it" is, but it must be powerful to snatch Parallax. I don't think it's Hammond because he seems really upset/afraid about "it" having Parallax. I hope it's something new we haven't seen yet.

" ME "

Maybe "It" is Hammond, and it was some other resident. But we know Larfleeze has the orange beast, and Atrocitus has been sensing the beast of rage.

" Guy also has a Green Ring AND a Red ring. "

 dove will be the first white lantern  maybe if there even is one?? 

Whoever's collecting the Emotional Entities is probably insanely powerful or at least possesses the knowledge and technology to entrap them, as the Guardians of the Universe have done in the past.   It could be an old foe of the Green Lantern Corps that we haven't seen in a while or who we've never met (Atrocitus and Larfleeze are all good examples of Green Lantern foes who's existence or at least full histories were kept secret from the Corps by the Guardians, it wouldn't surprise me if yet ANOTHER old enemy of the Guardians is out there gathering the firepower needed to destroy them).
 
The question is, if this unseen foe were to gather all the entities, what would he do with them?  Is it possible to harness all their powers together and use them for some purpose like empowering himself?  Or are we dealing with a Lex Luthor type of baddie who's inflated ego blinds him to the dangers of messing with forces beyond his comprehension? i.e. trying to combine all the emotion spectrums together by force could wipe out the universe or something.
