If she was grateful, she was at least grateful of the fact that what she recalled was currently a lot more then yesterday. Alongside the notes of her ancestors that she'd translated before the loss of memory made her sure that he wouldn't be able to hurt her, and he'd still be bound by her commands. Not all of them she imagined, but enough to keep him here and out of harms way.
This place hardly needed a Count running around creating chaos and ruin. And from what she could pick up from the cursing, he'd at least encountered her ancestor once. Enough to wish a lot of ill on the line. Ironic really that she was to go through those same steps, like a dance that had been done before.
She straightened, "come out Count. You are not in your domain, nor in your lands. You are bound to the Hellsing line." She set her hand on the hilt of her sword, steady and determined. She wasn't her ancestor, and despite the gaps in her memory now at least knew her purpose and duty. And this way, she could see how much he'd forgotten and recalled at the same time and how much the magic was tied to will and choice. "I know you can hear me, so hear this. You are not to leave this house." That was step one at least.
