You have an overly crazy mother that takes you to Vegas. You later find out that she and the bane of you existence's parents set you up to spend the summer (And two months) with them. And then you wake up.. In a bed. With a person. Who you just might not like. Naked. This said person asks you a question that is out of this world! Something that you would never agree to in a million years! You would never marry him! Rewind. He tells you it's temporary and fake. You consider. Then agree. This all happened to Mercedes Alvarez. What would YOU do? Just remember, Alvarez, O'Donnell: What happens In Vegas, stays in Vegas. Got it?
