Very well. You are a person who likes to appear composed, and do appear even wary and cold towards others, because you protect yourself - perhaps some remnant from something that happened in your childhood. But despite that, you're... honorable, caring, obviously interested in keeping those you love protected.
That is why you keep an eye on everyone here, isn't it? So you will know what they are like, what they will do - if anyone is a threat to your sweet, clumsy vampire girl. [...] Or perhaps her brother, though I doubt you would mind much if someone were to... remove him from the equation.
