<puts my detective hat on and sits next to Rusty>
Ok, we know Drew took the video in the first place. Therefor he had to have complicity in the initial release and subsequent fall out. The BIG QUESTION is why did he do it, and did he achieve his intended goal? Why did he seem to think Jj would want to pick up where they left off 4 months after the manure hit the air circulation device? And now that Jj has told him what to do with his advances, what will Drew do next? He already said something to the effect of "this isn't over, you will be sorry."
We also know the people behind Xpress are not particularly concerned with fact checking. They are not beyond making up stories where none exist just to amuse themselves. That makes them the perfect vessel to release the video.
So, was the blackmail threat Drew's way to get Jj home and back where he could try to manipulate him further? Does he have some sort of contact on campus?
Do Drew's parents want/need something from Jj's parents? Can/would they try to broker a deal for a power marriage? Would not be the first time parents have leveraged a child's relationship for personal gain.
Ok, I have rambled enough. Jj is right this world would be much better if more people thought like Rusty does!
