The Young Prince seemed to have expected at least one to take the initiative in the excitement and jump to him in order to claim 'righteousness' so he was ready.
Of course, if it weren't for Eric pressuring everyone around in order to not allow them to act properly it wouldn't have been possible.
But that was the reality right now, nobody could do or say anything to deny it. All this situation did was oil up the rage within the Young Prince.
After all, it was his greatest enemy that had been the greatest help to him at the moment, and it wasn't something he could easily accept.
With newfound rage and anger, the Young Prince didn't even bother wasting his breath or asking the butler for permission, as he just plunged his right-hand fingers deep into the new target's throat.
