Ooc:Guys, you are awesome! OMG. What a way to make an unwelcome. Well, I hope this one answers your questions:

As soon as the doors opened, Henry tried to explain everything to the Bloodvain girl, but as a reaction for one of the most feared vampire hunters, she had to scream at him and start menacing him with a wand. All this was totally wrong for him. Why did I have to knock the door? Why did I have to be here for the first time. All this is so stupid.
"I haven't done anything to Briam. He was my best friend, just before... Well, never mind that. Briam was attacked by a group of vampires this evening, including me, but by then I didn't know who he was. So, my master gave him a potion that can actually reverse the vampire transformation." Henry said as he tried to avoid the wands all sorrounding him.
"Don't worry, that potion was actually made by me. I am sort of half vampire-human. I tried it and it simply didn't work well with me. But Briam, he's a really tough guy, no matter what happens, everything will work for him.It has always been this way. He WILL wake up in an hour. He won't have any kind of scratch on his face and no vampire traits. And you, blonde guy, could you get that wand away from me. And really stop looking at me like that, like if I was a freak." He said to the guy menacing with a wand.
After trying to explain himself, without any notice he was dragged to a dungeon. After a few minutes, the same Bloodvain sister came and made a whole questionary.
"Well, my name is Henry Brown. And as I just explained upstairs, I haven't done anything to Briam." Henry said in a very rude and grumpy manner, he hated explaining. He hoped this answer would make a good explanation.
