Since she had been left to settle in, she actually hadn't left much unless given express instruction to do so. She knew the freedom to exist among the pack lands was there and open for the taking, but it was still a difficult truth to accept. It was just simply more comfortable for her to be out of sight until someone came looking for her.
When a knock sounded at the threshold of her space, she couldn't help the pang of anxiety as she was greeted by an unfamiliar voice. Even still, she was quick to respond. There was no need for her introduction, as he was already aware.
Even if he didn't identify himself as one of Sirius' sons, it would have been an easy guess. Of course, there were differences, but the resemblance was there from what she could tell- as long as she dared to look. "H-Hello." Adelina greeted, adverting her gaze to the side. She was caught in a difficult headspace of trying to force herself to be more conversational, but at the same time, trying to answer with trained responses. Needless to say, it left words difficult to come by. "Thank you ..." She started. "For taking the time, I mean." A sentiment that seemed appropriate for the given address.
