Fayt comes across as being a mostly emotionless, cold child, focused solely on his interests and his vow to protect his sister. For him, the most important thing in his life is his twin which is the only blood kin that he knows. He is prone to being over protective with her to the point that he always scolds her whenever she hurts herself. He loves his twin more than his self.
Though he is capable of portraying himself as a charming, cheerful, lenient individual, typically when on the presence of his adoptive parents, he is quick to revert to being unsympathetic when he no longer has to hide his true self. Fayt is a person that doesn't like to admit defeat, and it's with this stubborn behavior that he'll push through obstacles with a single-minded resolve to win, to advance, and to do anything and everything perceived as necessary to achieve his goals.
Despite everything, however, under the surface there's still a 10 year old boy. Prone to acting egoistically with a self-centered point of view, he can be quick to irritation when his demands aren't met, and sink into a moody frustration when his plans are compromised.
The past reminders and the numerous things he's suffered through however, are just as difficult to let go of. Fayt has a obvious aversion to unnecessary touch- especially from that of strangers and even his adoptive parents- and his vulnerabilities lurk just underneath the strong-willed and reasonable person he often presents.
In his heart though, he still longs for his real parents and for some friends, but his own bitter words and the harshness of reality keep him from dwelling on it for very long. He is not someone who easily trusts anyone, he is afraid of betrayal but still, deep inside, he wants to meet someone whom he can trust other than his sister.
