I did it with him too and noticed that I had to do things different. I know I didn't need the cup. I always did something different with Terence (is that his name?) and I didn't scratch his back and so I didn't have to send the email to his boss lady, but, I did have to call her on the phone. There are a few different things from the walkthrough, depending on what different person or response you choose. all I remember from choosing Scully was that it wasn't that hard. I think the 3 things that you need are there already.
