When Zoey is upset, she watches Mister Rogers Neighborhood. Growing up in the US she watched a lot of PBS as a kid, and her favorite was always reruns of the sweetest kindest old man who talked to his audience of children with the respect and dignity that no other show that catered to people of that age quite did.
Mira and Rumi have no idea who this man is, but they are immediately endeared by his soft spoken voice and the way he greets his audience with the "Won't You Be My Neighbor?" song. Zoey explains to them how culturally important this show was back home, citing the episode where he shared a pool with Officer Clemmons breaking the color barrier. And how when she found out he had died years ago (she was too young to remember his death) she didn't leave bed for three days.
The girls quickly catch on that this is Zoey's comfort show, so any time they happen to walk in to see she's watching it, they immediately go into soothing mode. They make her tea, get her her favorite snacks, and silently cuddle up with her on the couch waiting for her to feel comfortable enough to open up. Zoey's usually ready to talk sometime around the fourth episode. After she has a good cry over whatever it is she's upset about, Mira and Rumi will start singing "It's You I Like" The first time they did this it made Zoey cry so much harder that they actually stopped, afraid they made it worse, but she begged them to continue. Now it's tradition, complete with pokes to Zoey's cheeks, boops to her nose, and extra tight squeezes. It always cheers her up!
