i have no idea of what will happen in the finale, cause everything could happen. and that's a good thing

I'm so sad that Betty is going to die, cause Don will also die, and the Draper kids will be orphans, and they (Sally) doesn't deserve that.
Also ~everyone~ have been saying that Don is the one to die when the show end's, and here is Weiner playing pranks on us.

The Community christmas episode with singing. Does that count?
