It looks like Bianca is eventually going to confess her feelings for JR and with what JR did with Amanda it seems like she might fall for her. I just don't think this is a natural move and I think it would bother some people if Marissa suddenly become gay but we shall see what happens.
David is continuing to use his power, but what a shock Ryan overheard something. They never let David "beat" Ryan, it is like All My Children's version of Jack and Victor from The Young and the Restless. Ryan will expose the truth and save the day for everyone, but I guess we have some fun David scenes to look forward to until that happens thouugh.
