The dhampir understands he has two roles here, one passive and already done, the rest reactive and dependent on how this plays out in the real world. Still, he came prepared, hearing his mother chide him for not doing basic things like pulling his hair back and then sweeping it up to avoid it getting in the way, ensuring that he has dark clothes that can be destroyed if need be, and carrying himself with a calm confidence rather than deep uncertainty. That last part is essential. He has to hope that there are no surprises in play, that he won't have to move with a vampire's speed to prevent damage or worse from happening. Through past experiments, he's determined the properties of his own blood. Bringing the Hexcore into it is where he still worries.

He says nothing as he starts the infusion. His fingers are steady, his breath is calm. There. It flows.

"Under your direction, then."
