Christian was skeptical, but nodded all the same. He would stay at Hogwarts as long as he was allowed. The castle was the only familiar place he'd seen so far, and had been someplace generally considered safe. Of course, reassurance or not, he still stayed within Helga's reach, close at her side just in case.
"okay.." Helga didn't have his complete trust, but that really didn't matter too much at this point. She'd come for him in the woods with a blanket, food, and the promise of safety. She'd been nothing but kind, so it probably wasn't surprising that he was already a little attached to the founder.
