Well, looks like Blackwall just completely reset his quest line.  After those two cut scenes, he turned himself in as Rainer or whoever at the execution.  I already went through all of this and more.  Why, why, why, why?  I was seriously enjoying this game and it is my first Dragon Age game.  
I have been so impressed after 74 hours of campaign mode play that I have been putting together a review of the game to say thank you to the Developers for putting out such an amazing product.  Now my game appears to be stuck in some kind of real life Fade Rift that is reversing the flow of time.
