ok so this episode finally hinted to the notion of time travel. Hinting meaning that its actually the first time (i think) that one of the characters says the word time travel or believes there is time traveling going on. But was the whole dream/concussion sequence for Des a way of the writers telling us that there is no time travel in Lost? Im confused.

i think its another ''hurley-snowglobe''moment where we just been denied the whole time travel concept...its addressed to us i think,with our theories and obsessions :)
