Schizoid personality disorder
"Schizoid personality disorder is a condition where a person shows very little, if any, interest and ability to form relationships with other people. It's very hard for the person to express a full range of emotions."
Rarely showing emotion, it always appears as though Shayan doesn't care about anybody, sometimes not even her own self, keeping to herself and walking away from whoever approaches with a kind hand. And it's true. She doesn't care. All she wants in life is to succeed at what she does without shedding a single tear for anybody fallen in the line of work. That also spreads to allies of all kinds where she keeps them at arm's length because she doesn't want friends. And those that consider her a friend are 'deluded', in her words, as she doesn't want friends or need them. Those 'closest' to her she may spare in the line of fire, but that's about it.
When younger, she spent most of her time at home as opposed to grouping with people her age. While going to school, she was more an outcast and had to focus her mental energy on home life that was chaotic enough to leave her in constant turmoil. So it's safe to say she never learned how to form relationships or bond with people, not even her own family .
Further more, while her emotions are wholly in tact, she really doesn't want to show weakness and react, only ever displaying anger and agitation in some circumstances. Again, growing up in a bad home life, she never learned to actually process emotions properly, so any she does show seem odd, erratic, and even over the top, if only of the negative type. The bad home life also links in to her not having much sense of humour and the inability to react to praise and criticism, though the former she does crave in an odd way; her father being bad to her and her family alike, she wants to be told she's doing well, hence she works hard day in and day out, though still doesn't know how to react when being told she did good.
Antisocial personality disorder
"Antisocial personality disorder, sometimes called sociopathy, is a mental health condition in which a person consistently shows no regard for right and wrong and ignores the rights and feelings of others. People with antisocial personality disorder tend to purposely make others angry or upset and manipulate or treat others harshly or with cruel indifference. They lack remorse or do not regret their behaviour."
Shayan knows right from wrong and doesn't care one bit. She does what she wants, where she wants, to who she wants, if for herself or for Rocket. She will bully, harass, even manipulate people to get what she wants when it comes down to it, though it is a rare thing for her to bother.
Other people don't matter to her, generally speaking. Everybody in Rocket is fodder lest they be equal or above her in rank. People are expendable. Truly she lacks the care to save someone's skin unless it has a benefit or she's feeling oddly out of sorts, taking pity on very, very few people in which she sees her old self. Again, it's very rare. And if someone falls because of her, she doesn't give a damn, at work or outside of it. To harass someone into doing her bidding and once they've run out of use, she will happily discard them without second thought. Anybody who is hurt because of her actions doesn't matter. She just doesn't care.
