I think that’s actually the point of her character. Thalia isn’t reckless because she’s stupid. It’s the only way she ever learned to survive. Since she was a child, she was taught to fight back, lash out, and never show weakness. It’s a defense mechanism she built over years of living in that environment. Rationally, she knows the consequences, but reacting aggressively is the only survival strategy she’s ever been taught. In a way, it’s the only thing her mother ever passed on to her.
I know that, which makes her realistically made. I don't have any problem about how she acts. The issue is that it is really a common sense to not Kill an imperial princess and openly as well. Like she's doing like girlllll u can do better with that. It felt like a poorly written part yet it makes sense . you know what i mean

I really like the story, however Thalia's action is getting on my nerves but I understand why she's like this... she just so reckless! like even a dumber bitch knows that killing an imperial princess will serves you a death penalty even if ur an imperial princess as well!. like girl
