When Sophie and Cassie are in the kitchen, you can eventually hear Sophie humming "Shake Your Dragon Tail" in the background when she mixes the rice pudding.
Enrique: I've never seen a table this big before.
Cassie: You have to have a table this big when you have 72 brothers and sisters.
Enrqiue: 72 brothers and sisters?! Una familia grande! That's the biggest family I've ever heard of!
Enrique: Maybe you should stop trying to forget about your sister. Why not do something that makes you feel closer to her?
Sophie: You'll all look out for my little sister?
Wheezie: Oh, of course we will.
Ord: You betcha!
Enrique: I've never seen such a big table before.
Cassie: You need a big table when you have 72 brothers and sisters.
Ord: We're all invited to a going-away party for Cassie's big sister, Sophie.
Emmy: (after Max does an odd jig) That's Max's lucky dance. He thinks it helps him roll the numbers he needs.
Enrique: I don't see the grumbly bee.
Max: Yeah, we lost him! Now let's get to the post office.
Max: I won the ice cream sundae! Wish I wasn't so full of rice pudding.
"Moving On" features the first and probably the only appearance of Cassie's older sister, Sophie, who was first mentioned a little earlier in the season.
