[Vince Ferrer]

The difficulty in the black/white and color scenes in the first episode is that while the black and white part was a flashback, the events in both timelines were after the events of season 5. They are both "flash forwards" from season 5, and new to you, but the events in black and white happened some time before the ones in color.

My Glen prediction: Glen survives but is bitten. He will be given a hero's exit as he will save Alexandria from the walker army and lead them off into the sunset before the fever burns him out.

[Repeal The 17th]

OK
I just finished re-watching Season 6 Episode 1 and paid attention to the timeline.
All of the black and white scenes end after...
-some wrap-up of events from Season 5,
-discovering the walker quarry,
-saving Ron from the walkers,
-all of the planning for dealing w/ the quarry walkers,
-Carter talking about killing Rick,
-Carter holding a gun on Eugene...

It seems that the flash-back point is from
how they -thought- it would be to deal with the quarry walkers
to how it actually went down.
