I loved her when she appeared in the train and shut Ardyn's stupid mouth by freezing him, you go girl!!! Then she reveal herself to be one of the Six : Shiva, cool, totally didn't expect that. Though I would still like to know more about her, for example... she's presented as a Messenger of the Gods at the beginning, and then we find out she's one of them but how can she be alive if the Empire, or Ardyn himself, killed her? We can even see her "corpse" when we get off the train, I don't think I've missed anything regarding about this matter....
Also, Luna maybe did already know who she really was, since in the the train scene, before handing the Trident to Noctis, Gentiana tells him that she'll lend him her power as promised to the Oracle, or something like that.
Really cool character, I like her a lot more now that I've finished the game. She likes to photobomb which is really funny, I really wish we could see more interactions between her and main party
