Supposedly, if it's before Rian would have scoffed if someone said werewolves do exist, he conceded after he experiences it himself.
This happened when he's in his first year of college, he found out he is a werewolf. In the beginning he unexpectedly felt a little sick like any normal person would, hence he initially thought he just had a fever. However, after a day or two of being sick he started to feel a hot burning sensation in his body, followed with a sharp headache, his body started to aches and spasm like he was tortured by something and he felt his blood pressure rise due to the blood cells changing. As the minute passed by his rage intensified followed with his violence aggression.
Fortunately, at that time he was alone in his dorm while Rian and Ray were out in the bar or so, and Brian doesn't stayed much in their dorm, however at that time Brian suddenly came back and discovered him feeling unwell and observed him strangely for a moment and then immediately brought him out of the dorm to a place which was far from the city. The place Brian brought him was an abandoned house, it was deserted in the middle of the woods, as it was night time the place appeared eerily.
It was dark and silence in the abandoned house except the sound of Rian groaning in pain.
At that time Brian was gazing at him in a peculiar looks,like he was trying to figure out about something, however Rian was in extreme pain to care about him.
"Hold on, Rian this will lasted for at least five hours," Brian finally comforted Rian after he was sure of his conjecture.
"What the hell is wrong with me?" Rian shouted at Brian as his rage and violence intensified that he want to destroy everything around, even tearing his own clothes.
Brian, however just casually said, "You'll find it yourself."
This pain agonized Rian for over five hours which was almost like tortured.
After five hours, it was finally midnight when all of a sudden Brian too started to groan like his body was in extreme pain and then abruptly transform into a wolf which shocked Rian for a bit, when he himself started to feel his body was twisted in an unnatural manner causing him immense pain, all of a sudden his body started to grow hair, his eyes change into yellow with fangs in his mouth, then in a minute or so he instantly transformed into a hulking wolf like.
At the moment, Rian has lost his human minds and led out a long howl followed by Brian in his wolf form and instantaneously both of them run out of the abandoned house to the woods in a super speeds.
They remained in their werewolf phases until dawn.
...
The first light of the day shone faintly inside the deserted house. Rian woke up dazedly feeling light, his whole body feel difference and strong, however his muscles aches which he couldn't comprehend for a while until he heard a voice.
"Awake"
He turned to look to the direction of the voice and saw Brian sitting in the corner of the wall, half naked with only a pants in his body. Rian mind started to rewinded everything that happened last night until he turned into a wolf and after that everything seem blank.
His sense instantly came back and gape at Brian, "You're a werewolf?" he uttered in shocked.
"So are you," Brian said in a horse voice.
Rian mouth fell open as he perceived the truth.
"What's going on? Did I get a bite from a wolf or something?" he anxiously asked Brian.
Brian narrowed his eyes at him and said, "You're a half-blood."
"What do you mean?" Rian asked bewildered.
"You're a half-human and half-werewolf," Brian clarified him.
"What the hell? You mean to say one of my parents might be a werewolf!" Rian exclaimed.
However, Brian just shrugged and turned to walk away while saying,"The transformation will be painless from now on, except on a full moon", he pause, " You should stay in my apartment for a few days, you're are still new, you might not be able to control yourself."
According to Brian, half-bloods are known to be aggressive even in their human forms, but would have little problem resisting the urge to transform, and can be trigger to transform if they were to trigger, however as they grow older in age, the more control they can exert over their transformation, possessing full control of their wolf form. Whereas, Brian himself is a pure-blood, according to him there's a werewolves tribes that were rules by the Elders who are pure-bloods.
