Dont you think the characters from Lost are the same as Survivors?

abby = Jack (the leader, makes the decisions)
Tom = Kate (a fugitive)
Najid = Walt (the only young boy in the group)
Sarah = Shannon (self centered young woman)
Aalim = Sawyer (personality at the beginning is self-centered,
no one likes him at first)
Greg = Echo (they have plans of their own, but is changed
when they befriend the rest of the survivors)
etc.etc.etc.

haha just noticed this today. can you see the similarities.

and on top of that, we have "the dharma initiative( the people coming
up with a cure) and the "others" (Samantha's group of people)

also, both shows have a pregnant girlxD
