Pearl seems to have a hard time physically containing emotions (or controlling them at all). She shakes when she’s angry or really happy, does that spontaneous twirly thing when she’s gushing about the strawberry field. Then there’s the end of “So Many Birthdays” where she can hardly function when distraught.
