Maria: She'll either get mad or she'll start to cry... Or nothing. You never know with bipolar people... Though, be wary not to seriously injure her family... She'll kill you, that's a given.
Karah: WHAT THE HECK DID YOU DO? Karah almost never gets upset... So when you do manage to upset her, you'll be tracked down and tortured by her and Dharati. Not killed, as they might want to torture you again sometime. You'll be in some serious pain though.
Alene: You're dead. Not only will she target you, but Sabel, Maria, Selska, Mildne, Sten, and Thomas will as well.
Alex: HOW!? You really gotta try to hurt her, because she has little to no attention for her feelings.
Sabel: She'll just cave in, and Maria or Alene will tell you you fucked up. She isn't in possession of a lot of self-esteem and if you upset her, she'll break down.
Sten: You can't, as Sten doesn't give a single shit. It is literally impossible to get Sten to break down... Except for when you're really close to her.
Thomas: Or, he's too busy conserving energy he doesn't give a shit, or, he'll come after your ass and tell you exactly what he thinks of you... Intimidating, as he's about 1.85 meters.
Milan: He'll lock himself up in his room and mentally and physically beat himself down.
Kamm: Probably avoids you for a few weeks, but then it's all good.
Vars: He'll use his magic to either harm himself or turn invisible for a while.
Mildne: You killed a bird, didn't you? *sigh* Well, I guess it can't be helped. You better stay away from her for a while, she'll randomly shout at you when she spots you.
Stoje: She'll scream profanities at you for about an hour (or until her voice is hoarse), following you everywhere you go. After that, it's all good.
Sæl: He'll probably have a sad undertone in his voice for a while, not only to show he's sad but also to make you feel guilty.
Nysge: Just stay away. Don't even try coming near him.
Selska: She'll hug Ens and ask him what she did wrong. When he tells her she does nothing wrong (because he'd a good (boy)friend like that) she'll calm down and never talk about it again.
Uhygg: Again, I'll ask you how... But, it's easier for you to upset Uhygg than to upset Karah. She'll be even clingier towards Mærk and hateful towards everyone else.
Ens: He'll cry for a long time and will only let Selska near him.
Mærk: I know exactly what you said to get him upset, and you're a bastard. Mærk will lock himself away from everyone, and be alone for a long while. Not even Uhygg will be able to come near him.
Kama: He'll be the only reasonable person and try to talk to you about what you said. When you won't listen, he won't talk to, or about you for a long time... He's a person who holds grudges for a very long time.
Dharati: He hides knives in about twenty different places on his body. I am not going to say anything more.
