Quote from Orla in Episode Four
Orla: Which one's ours?
Erin: She didn't send a photo. Her family probably don't even own a camera. She'll find Derry a bit overwhelming at first, just because of how advanced everything is here. All the cracker stuff we have.
Orla: They have some pretty cracker stuff where she comes from, too, Erin.
Erin: Oh, really? Like what? Disease? Poverty?
Orla: No. You can get this wee woman made of wood, right? You pull her apart and inside her there's an even wee-er wooden woman, and you pull the wee-er wooden woman apart...
Erin: Are you talking about Russian dolls?
