Question: Who becomes the Enterprise's new first officer since Data's death? I know about the deleted scene which shows a new first officer meeting Picard, but since it was deleted I assume it never actually happened. The only person I can think of is Worf but does anyone know for sure?

Answer: It's unknown, and, with no TNG films on the horizon, will most likely remain that way for some time. Without information to the contrary, it's probably reasonable to assume that, despite the scene being deleted, Commander Martin Madden (the new first officer seen in that scene) does indeed take the position.

Answer: Shinzon was always intended to be much younger than Picard - the whole point is that he's a Romulan project that was ultimately abandoned - he hasn't gone through the accelerated aging process. Patrick Stewart could not have convincingly played a version of his character who was that young. And Tom Hardy does bear a distinct resemblance to a young Patrick Stewart if you look properly.
