Yeah, that's all I can recollect as well. A few absurd references *desiring* to attack Wu, comparing it to him flying from the rooftops with a cape "Assassin-Creed style", howling like a wolf or some bullshit. It is also not directly issued to her, and was a passing comment in one of the livestreams. Simply put, even if that can be taken as a threat, Jace's character had no means.
It is my understanding that if it came to a court challenge, Wu would essentially have to claim that she thought that threat was realistic. To which the judge would promptly reply "Get the fuck out of here". Different from a protective order.
