Jett

Personality Summary: 

Jett's entire personality can be summed up in two words: anger and edge. This boy has short temper like you'll never believe. The littlest things irk him to the point to scream at whoever dared upset him. He isn't particularly fond of other people; he spends most of his time alone to brood all edgily and such. To befriend such a kid is a near impossible task, but those who manage to accomplish it find that he is less grumpy with his pals.

Relationships:

Callie - Tolerates -  While he really doesn't like Callie, and frequently yells at her for continually trying to befriend him, a death threat from Cassie has forced him to be a little more polite when turning her down. He usually just tries to avoid her so he doesn't have to force himself to be slightly more tolerant than he would like. 

Cassie - Frenemy - Jett hated Cassie's guts when they first, like everyone else, but Cassie's equally defiant attitude towards him and her confidence to fight/say whatever she thinks to Jett's face has brought them close to each other in a way. Jett now actually kind of likes Cassie, despite they're constant, but he will never admit it. 

Ernest - 

Felix - Dislikes - Jett finds Felix's "emotionless act" (as Jett thinks it is) to be extremely annoying and therefore finds him intolerable. What pisses Jett off even more is how Felix doesn't seem to care about Jett's anger towards him. However, since Felix doesn't bother him, it's rare for Jett to have any interaction with him. 

Joe Bean - Dislikes - Like with Callie, he hates Joe Bean's friendliness and desire to be nice, even to Jett. It annoys the tar out of Jett that despite his constant rudeness towards Joe Bean, he refuses to show any irritation. Unlike Callie, Joe Bean doesn't constantly try to befriend him, so Jett does consider that to be a plus. 

Klaus - Dislikes - Klaus doesn't bother Jett too much, so Jett's opinion towards him defaults to disliking him. Usually when they interact, it's Klaus being on Callie's side and asking Jett to be more polite to her. This, of course, angers Jett. 

Maple - Dislikes - Jett finds Maple's skittish nature to be very annoying, and the way she freezes terrified right before running off is something Jett finds to be utterly insufferable. However, as annoyed as he is with her, he is glad she doesn't try to talk to him. 

Mary Sue - 

Naomi - Dislikes - Jett hates how Naomi tries to play "mom" with him, trying to get him to talk about his feelings and scolding him for being mean to others. He wishes Naomi would just leave him alone, but similarly to Callie, he just can't seem to shake her off. 

Resc - Dislikes - Resc is like an even more insufferable version of Naomi, who really goes out of his way to make suggestions on how Jett can manage his anger. Fortunately for Jett, simply making a few negative comments about how Resc is a robot just programmed to care about his "patients" is enough to get him to back off for at least a few hours. 

Vicci - Dislikes - He finds Vicci's combative attitude to be at least somewhat similar to how he treats others, but Jett finds Vicci to be more condescending and fake than him. At least he is honest about all of his anger and isn't trying to manipulate others. With that in mind, Jett even considers himself to be morally superior to Vicci and hates her for being even "lower" than he is.
