Panel 1: Maida, Zaynab, and Nat sit on the DLR train through East London. Maida is turned around in her seat so she can look out the window. This part of the Tube is above ground.
Panel 2: Maida turns to the other two, excitedly. Maida: "Blue sky! Real wind! Trees!" Zaynab, looking concerned: "Maida?"
Panel 3: Announcement: "South Quay Station. South Quay Station." The train stops and the doors open to let people off. Maida breathes in deeply and Zaynab shivers. Zaynab: "Ouf. Europe in winter might as well be Antarca!"
Panel 4: Nat: "Hey, uh, fanks for coming wiff me."
Panel 5: Nat: "My dad is a lot easier to take when he's got a audience to perform for. I promise I'll make this up to you somehow."
Panel 6: Nat: "I know you'd probably ravver be somewhere else right now." Zaynab nervously looks at Maida instead of at Nat. Zaynab: "Oh, ah..." Maida: "Are you joking?"
Panel 7: Announcement: "Crossharbour Station." The doors open again. Maida gets out of her seat with her things. Maida: "I haven't been outside since I got to this planet. I'm exactly where I want to be!"
