i think we played a very different game. Rio is manipulated by Quinn. isnt Quinn asks Rio about what she think, could she pass by her own?
nope, i think at the dorm party she reject mc while say "i am still taken". it would be logical to say, she have to said it to other diks too.
but as we know, you can duck Tara and she wont accept a kiss in next ep, because she has a bf... so, why would be Sally more honest.
maybe you can read his folder, what he say there... cheated on Danny with Rio only or doesnt say "only"
