So, you're all are probably going to come back to with "Duh, you idiot!" when I ask this question, but I'm just curious to see if anyone has an explanation.
Okay, so in the show, if you're time traveling and begin to experience the effects of the temporal displacement, Daniel says you need to make sure you have a constant in both time periods. ie, Penny is Desmond's in the episode where they talk on the phone on Christmas Eve. That being said, when Charlotte begins to feel the effects of the flashes, wouldn't the fact that Daniel interacted with in BOTH the past (while she was with Dharma) and in the present (as part of the science team)???
Is it just a matter of the time flashes being different than what Desmond and the freighter people were experiencing and what Daniel explains to Desmond? Anyway, any explanation would be greatly appreciated!
