What’s would a normal/average punishment be for unauthorized siring?

The campaign’s started to kick off now.

I just finished a session during part of a murder mystery (“who killed the prince?”), and as part of it had the “combat tutorial” where I show what combat is like.

See, this took place in an underground fighting ring for supernaturals. In order to get clues for the mystery, one of the players had to fight against a Kine.

One of the player characters frenzied during the tutorial against a human boxer and ended up ripping out the guy’s throat. Then he converted the exsanguinated human into a vampire in a “panic embrace” because he’s still trying to be a good person.

Obviously there’s going to be some punishment. But bro is a first time offender, didn’t do it on purpose, didn’t violate the Masquerade, and also is acting as interim sheriff (alongside the rest of his coterie).

I didn’t expect this at all (meaning that the player “broke Destiny” and did something of note) and am very pleased with this turn of events.

But how would a bland as bread prince punish this person? It shouldn’t be a full blood bond, but it shouldn’t be a slap on the wrist.

I would like a general idea of what to expect before modifying it due to other circumstances.
