Aiight, let's get this shit over and done with.
weevil
In no particular order or structure.
Rey's Jyn's character centres around daddy issues, both with Galen and Saw. Her early movie person appears careless and cynical, content to exist in the Imperial prison she found herself in. Her first instinct is always to fight, even against her announced rescuers. She's cold to the ideals of others and indifferent to their struggles. She goes along with the Rebels in their mission because it seems like she doesn't care enough not to after she is brought before them. Her moral compass does appear to not be completely devoid though, as she is seen risking herself to save an innocent child in the middle of a fire fight, something uncharacteristic at this stage.
Reunited with Saw, there's more cynicism and abandonment issues she takes out on him, who isn't without some paranoia himself, but when she sees her father again it lights a spark in her. She doesn't have much of an identity, growing up in Imperial privilege, then fugitive isolation, then trained as a guerilla warrior, she lacks personal motivation as her childhood and adolescence was taken from her, however the chance to redeem her father, a man she liked to believe was dead, gave her something to fight for, and when she fails to do so after his death, she takes his message on how to destroy the Death Star as her objective, finding what seems like something to fight for on her own terms (but only on deceased dads behalf).
More cynicism is expressed when the Rebel council vote not to follow up on the intel and she questions their legitimacy, her message though becomes more positive and she seems to be channelling the ideals taught to her by her Saw. At the top of the tower her first instinct is to attack Krennic's motionless body after sending the data tape, Cassian pulls her back and she eventually gives in and walks away, like a cleansing of her issues, that all came down to her fathers forced service of him. Strange enough when Scariff is fired on, she is content again with her fate and makes no attempts to escape the blast, despite having not long ago regained her purpose to live. With Cassian on the beach she reflects that they've done some good and their sacrifices, as well as her fathers who she held dear, wouldn't be for nothing, and that the Empire that took so much from her would soon be getting some back.

Right so now that load of shit is done can we agree neither Rey nor Jyn is a character devoid of identifiable personality and traits?
