Since this sequel is taking place several years after the first one,that means that the humans have had time to grow replacement Avatars (Norm) or new ones (new protagonistic humans).

I have had ideas running around in my head for quite some time about new Avatar drivers......I would post them here but they will be included in the next fanfic I work on.

Can you guys think of any?

Possibly... Norm's might not actually be dead, but I'd guess they'd probably do one for Max at least, as well as a new one for Norm if his did die.

Yeah, its still a kind of "up in the air" thing. They've got the knowledge and people, just not sure if the tanks they have are designed to house the infant forms. If they are, great, if not, well, we shall see what happens.

I'd guess they are...

Jake: They've got big
Norm: They fully mature on the flight out

I kind of feel that poor Norm is out of an Avatar. The ending shots show him and Max with guns. It would be great for him if they did repair his avatar or at least got him a new one.
Norm and Tommy were supposed to be the next step prodigies for the program, now everything is thrown out the window. Jake is now full Na'vi, Norm is out of an Avatar when that was his dream all his life. Max I don't think was supposed to have an Avatar, he was one of the support crew, but there are at least four other Avatars there. Going to be really interesting seeing how that all develops.

I'd guess that the humans leaving would be at most a few days after the battle... Norm's avatar was injured, and probably still resting, or possibly in one of those tanks to heal.

If they do, there'd be less scenes where Na'vi and humans are interacting. I want more of those, it reminds me that the Na'vi are aliens, and also I'd like to see how they are accepting some of the real us as friends.

Hmm... I believe there won't be any new Avatars. After such a failure, the project should certainly be abandoned or cancelled (the later is more dramatic, could actually imply the destruction or return to Earth of all the produced material)

They aren't going to be able to after being kicked off Pandora

I'm betting that the Sky People won't give up and will send other colonies to Pandora.

Pfff.. Max as an avatar...

*chuckles*

The Na'vi might request the humans to take everything they brought there to the Earth... as a display of force.

We were told that making avatars is incredibly expensive. Now, as the colony on Pandora is more or less self-sustaining, and it was possible to build avatars there, it would mean that building them is practically for free. Doing something there doesn't cost anything compared to going and coming back... It would be equally expensive whatever you did there. So I don't think they can made new avatars there.

About Norm:

1. Personally, I liked him better in his human body. His Avatar didn't seem right. I think his Avatar body made him look too silly, or I don't know, it somehow didn't fit him. It might be because we barely saw him in his Avatar, but that's how I felt.
2. He was somewhat funny, acting a bit childish when expressing his feelings, and slightly absent-minded and/or unprofessional. He forgets his pack, fails to use the sample correctly (when he has trained for years for this), and wasn't too happy with accepting the reality when Jake was chosen by the Omaticaya in the deleted scenes which I found unprofessional for a scientist, though somewhat justified.

Now, I think scenes like the one with the saliva and the pack would have been more amusing if Norm was as small as a Na'vi child. So if Grace is resurrected and resumes her duties as a scientist studying the beauty of biosphere on Pandora, with Norm as her right hand, and Grace mentoring him, I picture them better with the size difference and Norm without an Avatar. I think it fits his image pretty well. And he's metaphorically smaller than Grace, isn't he? It would be cruel but amusing nonetheless. And then they could put him aside the real Na'vi children, and make them laugh at him. Hm, nope, that would be way to much.

Another thing is that hundreds of Na'vi were killed in the final battle, and the victory wasn't all that happy because it came at the expense of a great loss. The thing that relates us best to the lost are the characters that were gone - Grace, Norm's avatar, Trudy and Tsu'tey. Well, if we bring half of them back, it would kinda make the our share of the loss mean nothing. And that's why I'd like his avatar to be gone for good.

And without an avatar for Norm, there won't be other new avatars...

The marines, perhaps, although the ISV has extremely limited space. We see scientists in Avatars with the Na'vi in the scene with the humans getting into the shuttle, as Jake says that they were chosen to stay.

Trudy and Tsu'tey aren't coming back, and we still don't know what Grace's reappearance will be.

Avatar was done with a LOT of attention to realism and I really doubt it would do that just because some people who don't understand that dying instantly from an injury is very rare (brain, spinal cord or complete body destruction excepted) just because some people expect that to happen because it does in other films. After all, norm gets out of the link, grabs an assault rifle and heads towards the battle to try and save his avatar.

From what we've seen it's both realistic if it is dead and if it is alive. He grabbed his rifle to join the battle. We don't know whether he could and intended to save his avatar. His avatar was supposed to die (as the deleted scene would suggest) but then again its removal might mean there were second thoughts on the matter. We don't even know if James Cameron knows whether he'll revive Norm's avatar or not. But I think it will work better if he doesn't.

I also just noticed that his original name was supposed to be Norm Cheeseman. So he was intended to serve as a comic relief indeed? Good thing that they cut down on that at least a bit. But still going as far as taking his avatar away from him is OK.
