Molly is a sharp business woman, and she knew how to close the deal. Jason is weak, she'll be able to lead him around as she has. He easily sucumbed to her obvious power of suggestion. What do they have after the passion and the competition is over? But I'm sure Molly will tell him what he will do, and feel, as she has. Melissa had warmth, a heart. He never felt so loved, although he clearly never deserved her. He took her love, filled himself up on what was lacking, then went on to another.
He will likely be cheating on Molly in time, after all, he is so miserably weak and pathetic.
They're hardly headed for something mature, serious, such as Trista & Ryan who are married, raising a family.
Molly's no fool. She knows her involvement in this will bring her more free press and opportunities.
Jason deserves to have her use him and trash him as he has done to others. The old golden rule still is in effect.
This show did nothing for viewers who have had trouble trusting.
