Recently re-read the Lunar Chronicles and it's really funny how all of the boys immediately lose their damn mind when they're separated from their girlfriend and she's in danger.
Wolf is obviously the poster child for this, but he and Thorne actually lowkey switch attitudes when they get to Luna. Wolf is reunited with his mom and has had some time to mellow, while Thorne gets the Stressy Aggressy Depressy treatment because they lost Cress on the way in. Jacin is known for ALMOST always keeping a level head and a deadpan demeanor, but when he and Cinder are in the terrain cruiser to save Winter from letumosis, he drives that thing with no fear of death, gods, or pissed off cyborgs.
You'd think Kai would be better about it since Cinder can very much handle herself and he assumes she's a genuine criminal for about half the series, but NOPE! SIKE! Even when he's almost convinced himself she's a crazy fugitive who manipulated him the whole time, he still keeps her foot on his desk, thinks about her all the time even when Torin REALLY doesn't want him to, and can't bring himself to be upset that they haven't captured her (just that she can't explain herself to him). He even successfully guesses her plan---overthrow Levana and put Selene back on the throne---but it's only part deductive reasoning. The other part is that he is actually losing his marbles and that hope is his last tie to sanity.
I have to imagine they had a conversation about this at some point. Like
Wolf: No, Scarlet, really, ask everyone else, I sorta lost it when you got captured.
Thorne: He really did. He was moping around staring at canned tomatoes like they held the secrets of the universe
Iko: Awww, cut it out, he had a good reason to be so upset! We were all worried about Scarlet. Besides, I seem to recall you weren't exactly a ray of sunshine when you thought Cress got captured
Cinder: Seriously all of you. I mean I get it, but you should have seen Jacin when he found out Winter got poisoned. I thought I was gonna die just from being in the blast radius. I'm just glad Kai can keep a level head under pressure because I certainly can't.
Kai who deeply admires Cinder for her resilience, resourcefulness, and determination, watched her survive like 10 highly personal murder attempts and lead a whole-ass revolution while keeping herself and the crew together, and who was actively having a mental breakdown for all of Cress and most of Winter: . . .
Kai: Right. I am the pinnacle of emotional stability. I am sure Torin would love to tell you all about how emotionally stable I am.
