Celia and Ham are on a weekend vacation, and Bex needs to go out for a few hours to run some important errands. As such, she hired a babysitter ahead of time, to take care of 13 year old Andi Mack. Of course, Andi wasn't too happy at first that her mom feels like she needs a babysitter. However, she eventually came around and wants to see how things go. With that said, the time arrives to discuss everything, such as babysitting time, what to expect, etc. And as you knock on the door, Bex opens it and gives you a warm smile

"Hey I'm Bex! Are you the babysitter?"
