Hemsworth is Safiya’s best friend. She’s admittedly a huge part of his life, and he tends to  be really moody and mean when parted from her. Hemsworth likes going through many phases, and goes with whatever seems cool in the moment. As a vampire, he could freely change his appearance, and he takes advantage of that ability often since he likes dressing up and changing styles. Hemsworth is also well liked for being a rather "cool kid", though does have a nasty personality. He gets away with it.
