Few crazy thoughts here:
It's inevitable that Walt and Jesse become reunited for at least one final scene. There has to be some remaining dialogue between them to end the series. Perhaps Jesse lives, perhaps he dies for his crimes- no idea. But I'm certain they will speak next episode.
Additionally, I can't help but notice some odd things within this scene:
I'm watching Walt's face, and if you mute it... it looks like he's apologizing. I know that there is a moral argument about Walt, and his identity, but this scene looks like Walt is saying sorry for watching Jane die. (maybe I'm looking into this too much, but the 2 eagles soaring together also seems to signify something as well.... perhaps that Jesse and Walt's respective fates are the same?).
Additionally, I think there's more to Todd and Walt's relationship than meets the eye. It seems awfully too convenient that Todd steps up and saves Jesse, while also giving Walt a barrel of money. If Walt wanted Jesse alive, protected, and preserved... that's the way to do it. Things went out of wack, and waaaayyy off course, but Walt may still have gotten his wish.
Obviously no-one knows what's going on, but I have some sneaking suspicion Walt is still has more control than we are led to believe, but will spiral out of control a la Scarface.
There are obviously some gaping holes in my theory, but I'm bored and it's fun to speculate
