Here is how Tommy and his friends read in the Library and how they were picked up to go home in Welcome to Canterlot High.
Tommy Pickles: Excuse me.
Cheerilee: Why, Hello there. I'm Cheerilee. And you must be the new students Vice Principal Luna told me about.
Chuckie Finster: Yep, That's us.
Rarity: It's their first day.
Twilight Sparkle: We're here to explore the library.
Cheerilee: Well, Feel free to have a look around and please keep quiet.
Later, leaving the library.
Grandpa Lou: Hey, Sprouts.
Tommy Pickles: Hey, Grandpa. Thanks for giving us a ride home.
Chuckie Finster: Yeah, We had a great time at Canterlot High.
Grandpa Lou: That's good to hear. Hold on tight, Kiddies. We're goin' home!
Twilight Sparkle: I tell you, Spike. They sure enjoyed visiting our school from time to time.
Spike: I'll say.
