For those who have only seen the 55-minute sneak-peek, and maybe if it was not addressed in the 72-min Comic-Con showing, we can easily have been shown only part of a certain storyline! Is "Genesis" supposed to be an hour-and-a-half premiere or just the 55 minutes that has been leaked? Was the 72-minute screening a combination of the first two episodes or is it more of Genesis? A 2-hour show without commercials ends up being a few minutes shy of 90 minutes. So then it's possible that if the premiere ep Genesis is a 90-minute show with limited commercials, then that means there could be a lot more to the premiere that has purposely been left out as a surprise! A lot can be shown in even 10 minutes to put a new spin on a story!
The point I wanted to make is that although a certain person's experience (let's call him the Rock for spoiler-free-ish content) at the end of the 55-minute showing seemed more real than previously similar ones, is it clear by what we've seen that that was the real experience? It's easily within the power of the storytellers to still have that last event just be a more in-depth dream! And so then what we may have been shown was a dream that helps us understand a little more about another character's potential through one of the Rock's abilities.
If you look at the current spoilers for ep 105, the character which the episode may seem to focus on isn't mentioned yet, and that would make me think that the Rock whose experience I'm referring to at the end of the 55-minute sneak-peek may finally have their "real" experience in ep 103, since it wasn't a revealed spoiler. That makes sense to me, considering the episode title that alludes to a
famous Neil Armstrong quote (at ~ 109:24:4

. OTOH, the ep 103 title may refer to what Mohinder finds, or an action Claire takes, too. But does it sound plausible that the Rock was just dreaming?
