I don't see why tbh. The competition was over, how would they be able to prove anything. And we know for Ruby and Sasha it had nothing to do with the competition, either they like it or/and they thought it was a good opportunity to have connections (and a good job, it's not a crime to give jobs to whoever you want, even if it would be bad publicity).
Also, I didn't see the dumb girl in the party (don't remember her name, she was the the least hot of the four : o ). After all she was more pure than the other ones, she "only" had 8 guys until now ahah : D.
Anyway I think MrDots made D lost this pageant so that the story stops developing around D's career, and so that all the characters stop being so far from each other geographically speaking.
For example:
Jennifer indeed didn't get much action despite being in the game for so long. The characters are generally far from her in terms of geographical location, and even when it's not the case we don't see her as much as you would expect. To a least extent, I'd almost say the same for Elena.
These two should have been banged together in every way possible long ago.
I think MrDots just want to finish the game in a fixed location (probably), with the important characters generally close by. At least those two.
So unless there's a way to win the competition, I think the modeling "phase" is over.
