OOC:If I say something about what you said and thats not the way you meant it, chances are I read it wrong or misinterpreted it. Which to be honest, unfortunately happens a lot with me. If that happens, just try to explain what you meant more clearly, arright?
Regardless, unless there is a actual, valid reason to nullify the topic(which misreading what someone else said may or may not actually count, depending on severity), it cant be nulled. The character behaving out of character maybe, but I dont really see him beating up anyone in the topic, more lecturing them. And to be fair, a goody two shoes of any kind would be out of character to beat up on anyone at all. All in all, I still dont see anything wrong.
Stalling NPCs or normal characters merely shows that the threat is dying. Its likely that he cant think of any way to advance the story and is, therefor, leaving it up to you to do so, which you clearly aren't.
As for Zak simply not posting in it(which I forgot to refer to in my earlier post), er, you could always just consider the topic over and move on? Its your character, and if Zak neglects to post in three days or so just post yourself about the character leaving, adding whatever flesh to the post you want, then move it along to the next topic wherever or blah(within reason, of course; for example, if your character CANT just up and get away then you'll still need to RP that part out or blah).
