I get out plenty, thank you. [He says it a little too defensively, as if this isn't the first time he's had the accusation that's leveled at him. In many ways, staying in the castle isn't a choice. But Alucard does not suspect he'd enjoy much of being among other humans, even if the act of travel is something he would doubtlessly enjoy.]

I can go get a map of the area for you - it'll be to your long term benefit.

[Hector may need to know the area better than just turn right at the big tree. Of that much, Alucard is confident. There is a pause in him though, aware that he hasn't asked an important question.]

Will you need food and other supplies? Forgive any rudeness when I say your task at hand seems to have discouraged proper packing.

[Hector is also 200% right about the fact Alucard would refuse the dog, but only because he'd be expected to.]
