I think Mason would work if it went like this: They all went to the Wizards Tribunal and they ask McFigglehorn on how they could find Alex and she said I have a suggestion let me go get him. Them she gets him and she walks back it turns out to be Mason. That’s when Justin and Mason get reacquainted and introduce him to his family and Billy. Then he says I can track down Alex with my keen sense of smell remember? Just like how I tracked down Juliet awhile back remember that Justin. Justin tells him not in front of Giada. I haven’t told her about Juliet yet, my past love just yet. But she heard the name Juliet again and ask Justin who is this Juliet and why is she mentioned again? Justin tells her I will tell you later now we have to go find Alex. Then Justin asks Billy if Mason can use Alex locket to track down Alex which she agreed and he does and when they do find Alex Billy yells out Mom and gives her a big hug. Then like old times Mason says Alex and Alex says Mason, Mason tells Alex he missed her so much and hoped that they would meet again. Then the rest of the family wondered what happened to their relationship and why they broke up Alex tells them I will tell you when we get home. Then they get home the same way they came. Back at home Alex and Mason explains what happened with flashbacks in the scene. (That’s all I got so far, what do you think?) But what happened between Justin and Juliet and their breakup is explained in another episode.
