(about the poll)
Jake, we know, had a twin brother, Tom. Its existence made it possible to justify the creation of Jake's avatar, while allowing us to discover Pandora through the eyes of Jake, who had just joined the Avatar program.
But the existence of this twin also offers a great scenario possibility: flashback scenes, even an entire film, with Tom Sully, while keeping the same actor. This would be consistent with the often formulated assumption of finding Grace Augustine and Quaritch during flashbacks. What do you think ? If this assumption was obvious, spare me the tomatoes, this is my first post here! ; )
