Both parties are young enough that their sires may well choose to get involved. The culprit's sire has the right to accept punishment in his place, though I think it's unlikely that they well. They seem to be trying to remove themselves from the situation entirely. The victim's sire may choose to demand reparations, likely from the sire of the culprit, the one who has something worthwhile to give, rather than from the culprit themselves. It would be unusual after more than ten years since turning, but not unheard of if they can make a case that the loss of the victim was a terrible blow to them. It doesn't seem that the victim was particularly valuable to or beloved by their sire, but that doesn't mean that they won't claim that they were. It doesn't seem like a situation in which Dracula would have granted whatever reparations were demanded, but you need to be ready to argue that. They may also argue, as an injured party, for the execution to be made public. You can deny this, but I'll need to go through the old execution records again to find a good reason for it.

[ It's all more minor, it pales in comparison to the terrible thing that must be done, but every detail is something that Alucard will need to be ready for. There is no official code of law for dealing with this situation, only a century and a quarter of Dracula's decisions. They're lucky that he was apparently incredibly consistent in those decisions. ]

Dracula didn't take kindly to sires using squabbles between the younger vampires to gain influence. If all else fails, you can remind them of this. And-

[ Fuck, this is a lot of shit to expect him to remember and be ready to tell potentially confrontational shitbags about on demand. ]

-I'll have Sypha help me make notes of all this shit for you, too. Once a date's been chosen, we'll take the day before it to go through all of this in detail, make sure you're prepared.
