1 hour ago, Animewarsdude said:Her fate is detailed in Dark Disciple which I think was adapted from two episode arcs (8 episodes) that would have been covered in season 6 and 7 of Clone Wars but due to the show getting cancelled it was never animated. The reason she is a pilot for the ship though is because that class of ship was originally created to be her ship for those arcs but they changed a little bit and ended up reusing it for Rebels instead.
The point is that we do have at least one pilot already in the game that died between Star Wars Episode II and Episode III. Certainly there are plenty of other cases of ships, pilots, and crew that were possibly alive (or known to exist) in this period that are also in the game - but there are always those that argue against the significance of those because they might have also existed outside that period (and, of course, we know some DO, so...yeah. Anyway.)
Someone canonically dead before Episode III starts, though...that basically puts the nail in that coffin.
