It was the guy who Negan killed in last week's episode that let him out.

I had previously thought it was Carol, but once I watched the episode following his escape it was clear it was the douchy guy he killed with the rock.

 

I still say Carol. Aaron would really surprise me, so that's probably who it is.

 

Hmmm.. That's an interesting take that I could see making sense in the end if Aaron did it.

 

I assumed Carol. Carol would do anything if it hurt the Whisperers, and she knows Negan would.

 

I don't know, its usually not Aaron's M.O. to be sneaky like that and do something that he knew if the council found out he'd be in huge trouble, probably off the council. He uses reasoning to get people to see his point of view or plan, and he is loyal to the workings of the council. Its definitely not impossible, but Eric died due to the war with Negan, and I'm just not seeing it right now. Carol is being very deceptive and sneaky right now, with little to no loyalty to the council's decisions. She still has my vote.

 

I can't see Aaron doing that. He might have had second thoughts about voting for Negans death, but he could just have changed his vote the next morning.
I haven't considered Carol either, but it does make sense. She might anticipate, that Negan would cause trouble for the Whisperers or at least keep them occupied, while she figures out, how to deal with Alpha.

 

How about Lydia? She has the most incentive to let him out.

 

I think if it were Daryl, he'd just admit it. He's always owned up to his actions, even the misguided ones. He certainly wouldn't be wasting his time pretending to look for Negan if he'd let him go.

My money is on Carol. I think she felt that unnecessary energy was being spent on worrying about Negan when their attention should have been on the threat of the Whisperers. If Negan was willing to try and take some sort of action against the Whisperers, so much the better.

 

My bet is Carol too. She seems to be the only one in ASZ that is eager to kill Alpha to revenge the death of Henry (personal level) and to break the border 'treaty'. But, it would be interesting to see how she convinced Negan to go to infiltrate the Whisperers.

 

I still think Carol. She was looking to kill Alpha, now she just wants to destroy the herd. Something must have shifted her goal, and that’s why I think she she told Negan that it has to be him that kills Alpga.


The truth is out there

 

It could also be FG. He is the swing vote. So Negan will live or die by his vote. Instead of casting his vote, he let him out. Yes he was the one who found him gone, but that could have been an act. He may be thinking even if he voted to keep Negan alive, someone would/could get to him and his life is in danger.

Another question, does Negan know who let him out? Did someone come let him out or his cell gate suddenly unlocked without him knowing who was there?

 

Judged from his reaction to Brandon asking about his escape, I would say Negan knew who let him out.

And, whoever that is, s/he must also ask/bargain with Negan to go and deal with the Whisperers (maybe that is a condition for his release?). This can explain why when Negan got out, he went after the Whisperers. It seems he is on a mission.　

 

Siddiq also has blackout periods. Last episode he suddenly realized he was up by the windmill with his baby. So anything is possible.

 

Said everyone in Alexandria​

 

I can't see someone letting Negan out with a precondition that he goes take the whisperers out. It seems against the personality of Negan to agree and comply. I think Negan went to the whisperers on his own to do whatever he is planning to do.

Could it have been one of what's her name's (the one who Negan killed by accident) friend, went to his cell with a stolen key in an attempt to kill Negan for revenge, only end up being overpowered by Negan? Negan then escaped, and the guy kept his mouth shut for fear of getting into trouble with the council.

There is also the possibility that Negan let himself out, that he has already picked the lock for a while, and could have left whenever he wanted. He left once and came back on his own, they were no longer watching him that close. He could have made a workable pick for that cell just in case.

 

Hmmmm. I think this is a very interesting idea! I'm not a comic reader, but doesn't Negan return to his cell after escaping in the comics? Maybe this is something of a remix of that idea--that he's had the ability to leave for some time, but has opted to stay hoping to earn his freedom legitimately. With a death sentence potentially hanging over his head, it may have seemed a very good time to exercise his option.
