That whole statement was just odd and stupid, like almost to the degree that QX appears to be only pretending to support BB and is actually encouraging her to reveal/say all that in order to incriminate her.
All that really needed to be said at this point was that the video exists, a few details about what it shows, and that law enforcement has it. It also would have been way smarter for him to say that without BB present doing whatever act she was doing over there. He could easily have said that she was currently meeting with law enforcement and that he had been tasked with reporting the existence of the video, and then there would have been no judgement of her demeanor.
All those details about the fight, the dick pics, the spanking, the possible molestation, and the failure to report other abuse by DV are the kind of thing that should come out in a trial if possible, not right now in the court of public opinion. Nobody needed to say any of that to show that DV is probably guilty, and if all those other details had been left out there would have been way less information on record about BB's neglect of Maleah and horrible decisions. At least if someone truly was speaking for BB the way QX is acting like he is. (I'm not saying she deserves it.)
