They need a level man haha. I kind of can't wait for both Clary and Jo to show their crazy. 

Now I just will need to think of what Jackie could do to upset Clary haha. I think that Jackie will likely be the one to take it to far. 

Logan will be half enjoying the show and taking care of Clary, trying to calm her down. As well as hiding her from the people that will probably be laughing. 

Jackie won't know what to do when Billie comes out, I can see all of the other vampires letting the two queens settle things one on one. Not wanting to get all the other demons involved in the fight. Jackie will get her ass kicked like she deserves.

Logan will just nod still smiling. "Yeah, I'm coming babe just trying to get her to stop crying." Then he'd pull Clary away from the whole crowd of people, ignoring the fact Jackie will be screaming cuse words at him.
