At the end of the first movie Sector 7 is disbanded.
In the second movie Simons had to run a deli shop to make due.

In the third movie Simons is back as an agent. I tend to think NEST is more of a military outfit.

I can see National Security Advisor Galloway getting even by reinstating Sector 7 under Simons.

I just don't see Simmons wearing NEST underwear.  

 

i dont wanna see simmon's underwear ever again anyway!!  

 

Yes, what a stupid and unnecessary scene that was.

Maybe since S7 is back, we'll see a resurection of Frenzy from that locked glass vase, (with some help of Soundwaves minions?)then Barricade is back in TF3! ( well in my world it would be nice )

 

Doubtful that Sector 7 is being resurrected. NEST is the group of humans working with Transformers now.

 

Then Simmons will be a NEST Agent?

 

Or Simmons could be working independently, which is what he was pretty much doing in ROTF, with his working at a deli as a cover-up.
