I don't see the point in it being a dream. I mean it's gonna happen eventually, so what's the point in wasting time filming a dream only to see the exact same thing later? Who knows though.
Also, no one should be judging anyone's expression. They might not even use that take in the actual episode. It's a few seconRAB of screentime. When you take pictures, sometimes you make weird faces in certain frames. Same thing with episode stills. So...whatever.
I didn't watch it until just now because I was in a horrible mood earlier and I didn't want that coloring how I felt...and now I wish I didn't because I hate all the wank. *SIGH*
