Is she Thalia Grace in th next Percy Jackson?

Even though Kaya is a wonderful actress i wonder if she is the right person to play Thalia. The reason why she was not chosen to play the lead in hunger game was that she seams fragile and can not support the role of some one who is tough. I agree with this statement. Thalia is like the charecter in hunger games so it does not seem likely that she will play the role of thalia if she did not get into Hunger games. Also i dout that they are casting the movie now when they are still makeing the script. And she had not metioned it on her personal twitter and or facebook and there have been no remarks of her playing the role from the producers, actors, directors or enyone else. Therefor i've been lead to belive whoever said she'll be thalia is wrong in thinking that she is or just lieing, what do you guys think? And please no critisum of the actors, movies, me or enyone else.
