The timing is completely off in this episode, if it is 1988 when Rousseau landed on the Island, then Ben is supposed to be in his 20's and Charles Widmore is supposed to be in his 40's, but the characters look significantly older than they're supposed to. And when does Widmore get off the island then? Isn't Penelope supposed to be born around this time? Assuming that Penelope is supposed to be in her 30s despite the fact she looks like she is in her mid-40s, then this whole aging thing and time travel makes no sense. Although Lost is a great show it is one of many that shouldn't dabble in time travelling if they can't precisely depict the correct age of their characters. This, by which I mean season 5, doesn't make any sense.
