So the finale is tomorrow. I'm freaking out sitting here waiting for it.
I went to AMCTV's website and to the blog section for Breaking Bad and people have a LOT of theories as to what the burned teddy bear/body bags mean/are/etc.
I think it's pretty ridiculous, but the prevailing theory seems to be that Donald somehow causes a plane that's carrying Skylar to crash over Albuquerque. How did all these people come to this conclusion?
The "flashback" episodes occur in the episodes with the names 737, Down, Over, and then ABQ (which is the finale tomorrow). So, 737 down over ABQ sounds like a plane crash. Plus, supposedly you hear a plane flying over when Walt is talking about needing $737 thousand bucks and it pans down to Jesse's skull keychain.
I think a plane randomly crashing would be ridiculous, but it's the main theory floating around. That, or the water heater Walt installed explodes.
