Serbek is, somehow, afraid of Ekmê. Even if Ekmê only is a creation of his mind, he believes in his existence. Ekmê offsets Serbek's weakness. He seems more powerful, stronger, colder. He is a kind of 'mask' behind Serbek is hiding when he does not feel like he is strong enough to face a situation. This mask, which is a second personality, a second "being", also is Serbek's greatest fear, which is paradoxical. Serbek can hear Ekmê's voice. Yet, he is the only one who can allow Ekmê control the body or not : it is difficult for Ekmê to impose his presence, excepting when Serbek is weak and when his will is gone or low. Serbek does not hate or dislike Ekmê : he just feels lower than him. However, his presence reassures him, even if he will never admit it. Moreover, Serbek tries his best to hide Ekmê : he does not like the idea that others might be afraid of him if they know that he is schizophrenic. He does not assume it. His advice toward Ekmê is paradoxical : on the one hand, his presence makes him feel safe and protected. On the other hand, he feels shameful about having to hide behind Ekmê. He sincerely believes Ekmê is real, and that he is not a pure creation. He also does not want to get rid of him, because he thinks Ekmê helps him building his trust in himself. Moreover, even if he had wanted to "erase" Ekmê, he would not have been able to recognize he could : he thinks Ekmê will forever stay here, and that it is impossible to make him go away.

Serbek and Ekmê's feelings towards a character are generally pretty much close, excepting if one of them has a conflict about someone. Yet, Ekmê may be more distant than Serbek is, and their opinion might not be the same everytime.

Ekmê is narcissistic. He thinks he is more powerful than Serbek, and really considers the latter as being inferior to him. However, his feelings toward him are paradoxical. He does not like Serbek's behaviour - the way he is weak and a bit childish and fragile. Yet, he knows he would not be real if Serbek was not here. Ekmê only is a creation, yet he considers himself as being another soul, sharing Serbek's mind in one body. He considers himself as being Serbek's "room-mate". That is why he will not tolerate any injure caused to Serbek : he thinks he is the only one who can hurt him and submit him, and he will never tolerate it if someone else does the same. That is why he is revengeful, and why he often takes the control of the body during a fight. We can say, in some, that he is "possessive" toward Serbek. He will never admit he likes Serbek, even if we can see in his behaviour that it can be, sometimes, the case. He will always hide it behind a kind of hatred, which is just a way for him to think he is superior, and that Serbek is a poor stupid guy. Moreover, his kind of "liking" toward Serbek can be seen in another way : Ekmê will always try to know Serbek's friend better, and even to show them some affection. Ekmê is a kind of mask behind a mask : he is Serbek's mask, but he is not that powerful, even if he will never admit it : he also hides himself. That is why it is paradoxical : Ekmê does not really exist, he is just a way for Serbek to feel better. Yet, both of them think Ekmê is real - yes, it is very complicated.
Since Ekmê thinks he is superior, he also thinks he is physically taller than Serbek - that is why the normal size is used instead of the mini-spell when Ekmê is controling the body. However, in reality, the size does not change at all, and Serbek's size also is Ekmê's size. It is only to express Ekmê's self-esteem, and how he views himself. Ekmê also assumes the fact he exists, unlike Serbek does. He does not feel any shame about the fact they are two in one body, and he does not mind saying it to Serbek's friends - which irritates Serbek a lot, however he cannot do anything against that.

Ultimately, Ekmê is not real, yet both Serbek and this second personality think he is. Serbek is the only one in the body, but he has to hide behind another personality to feel safe and better. He is very paradoxical and complicated, and his ideas may have no logical thread between them. Regarding his relations, I have mentioned in the "Ties" tab that they may be very close concerning some characters : as they are only one and only personality, which defines Serbek, their ideas toward another character might be the same. However, if they are not, it is only because Serbek is paradoxical, and so he may have a lot of difficulty to "cut" his feelings toward someone, and so to really know what he thinks about them. To conclue, Ekmê does exist in Serbek's mind, however he has nothing to do with a second soul sharing his body.
