[Buzz looks as the doctor grabs the boy’s arm to look.]

Buzz: Oh! So it is! Remarkable. That’s the work of spirit creatures for you.

Doctor: Spirit creatures? They can do spellwork? [She’s still holding the boy’s arm.]

Buzz: Most can’t, but some can. Excuse me. [He releases the boy’s arm from the Doctor.] The Forest Guardians for example, and their various servants.
