She knows that he'll handle the situation in his own way; she's just concerned that "his way" doesn't include protecting himself. She's afraid he'll sacrifice his emotional or physical well-being in the process of solving the situation, because that's what he'd always done in the past. She is trying to restrain herself since he asked to handle it alone; she just wants to know what his plan is and not be kept in the dark.
She also certainly has some overcontrolling tendencies, but I think it's pretty clear that he likes it that way lol.
I wish you could like replies because I totally agree
Lwk i'm getting a bit pissed off at letty bc let the man fuckin cook bro. She alr knows he's pretty clever and smart, and he'stold her he wants to handle this on his own. And it's not like she told faucon to inform her of the sitch if it looks like the prince is being careless with himself or his safety. I get wanting to support your partner and/or protecting them, but suffocating them in the name of protection/possession aint it????
But she's a kid at the end of the day so it's not totally fair to expect her to be super levelheaded about this ig
