In this scene, India's pet/friend Thelonius has gotten away from her and India's in hot pursuit. Thelonius has a penchant for disobeying the rules. Most of the time, he's just improvising, but I get the feeling that he always has a general idea of where he's going and what he wants to accomplish.
While outside, India and Thelonius run into some schoolmates of India. I wouldn't call them friends, necessarily. More like contemporaries, or associates, or arch rivals.
Here, the girls see a neighbor who lives on their street and the twins helpfully inform India of some of the neighbor's biographical information:
Kids say the darndest things, don't they? Once, long ago when I was in elementary school, I was eating a tuna sandwich at lunch. The kid sitting next to me told me that the dark spots you sometimes see in canned tuna are ground up pieces of rats. I was unable to finish lunch. To this day (no joke) those spots still make me pause when I'm eating tuna sandwiches.
So there's an appetizing bit of imagery for you. Moving right along...
Speaking of the traumatic: the twins are sorta kinda based on Delbert Grady's twins from "The Shining". It's one of my absolute favorite movies ever, and the scene where Danny runs into the twins in the hallway still makes me jump. This particular set of twins do not belong to Delbert Grady. They're just not all that nice to India. India would probably get along better with Grady's girls, assuming she could overlook the fact that they were ghosts and all.
