Rousseau didn't remember Jin because she never met him. Desmond didn't remember meeting Faraday because he hadn't. etc. Some things did seem to have already happened though, such as Locke meeting Alpert.
(SPOILER)Neither of your instances apply, though. 1) Dan acknowledged that Desmond COULD change time because his consciousness had shown the ability to exist in two different times - he was "special." 2) Jin and Rousseau were rarely, if ever, in the same scene together, and never spoke - the closest would be the season 3 finale when they were choosing shooters to blow up the dynamite. She's also messed up in the head, though.
