WOW!!!!!!!!! Just bloody wow! I was completely blown away by this episode. One of, if not THE best ever, in Lost history! I wish I had more time right now but just had to say it was so incredible.
I never thought I'd get my head around the whole thing after 'Flashes' but this was just amazing. It makes so much more sense now relating it to perception rather than basic 'time-travel'. I just loved it, so so good!
