She does say in the link that Cliff (the bodyguard of Jensen and Jarad) told her not to ask that question and just thank them and go, so I can understand stopping when she did as I think it was more about Cliff approaching her than it was the boo's stopping her from finishing. But then it made it more awkward to cut her off at 'I've seen some possible subtext', instead of letting her get to the gist of her question for Jensen.

Interesting that she said her question got through the screening process, yet that was obviously a question that the actors were not okay with being asked
