Okay, so we know from Richard that after taking Ben with him, he'll forget that the shooting accident ever happened. But still, he had many memories from his past (for example Annie, the wooden doll present, first meeting Richard et cetera). So, what if this is the same deal with Zack & Emma, you know, the two kids who were abducted by the Others in season 2. Maybe they were taken to the Temple as well, they forgot the crash of Oceanic 815, but still had many memories (like when Emma was asking Jack in season 3 how Ana-Lucia is doing). What do you think about this?
