Sym's writing postcards to Nikki and her mother, using special Antarctic stamps and everything.
Sym hears a sound—Mimi Dormiere-St.Pierre is crying in the bathroom. She and Sym bond over her loneliness. Poor Mimi lost her fancy phone, so she can't even call home.
Sym suggests Mimi go home on the next plane; so many people have been ill that Sym thinks she'll have company.
Mimi, who's a writer, says that Manfred is going to film one of her books. What a coincidence…
Mimi tries to gossip a bit about Sigurd. When she tells Sym that he's cute, Sym's enormously embarrassed.
When they hug it out, Sym tucks her postcards in Mimi's back pocket. Why is she being sneaky about it? Unclear.
After a chat with Titus, Sym is back in the tent. Everyone's asleep, and she's reflecting back on the days before her father died. He was drunk and mean.
Sym's been thinking about it, and she's pretty sure that Sigurd only likes her because of Victor. She's maybe overestimating Victor's appeal.
Sigurd has been hanging around a lot lately, which makes Sym think of a practical joke Maxine played on her once.
The joke was that Maxine told some boy that Sym would sleep with him. Great joke, Maxine.
Sym wonders if there's something wrong with her. Why isn't she more into boys? She finds them vaguely disgusting.
Anyway, Sym's glad to have Sigurd around. She talks to him about Symmes's Hole, and while he doesn't have a lot of answers, he is a good confidante.
Sigurd is still convinced that Sym shouldn't call her mother. (Why does he care?) Oh, and they're making out all the time now.
Everyone in camp is still ill. Everyone, that is, except Victor, Sym, Manfred, and Sigurd.
People are lining up to take the next plane back—they're ready to get home—while Manfred and Victor are there, ready to meet the film crew.
Except the film crew isn't there. Hmm… Seems a bit fishy. Manfred says he'll just go fetch them and come back on the next plane.
Victor seems pretty indifferent about the whole thing; he says Manfred will just have to catch up.
There's a meeting for all the explorers. Sym goes to fetch Sigurd, but he doesn't feel like coming.
Sym notes with some surprise that he's packing up. Evidently he's going back with his father for the film crew.
In the men's tent, Sym finds one of Uncle Victor's notebooks. It has tiny crazy person calculations and writings in it.
Oh, here's Manfred. And guess what? Everyone's going back to civilization. The trip has been cut short because everyone's so ill. Sym seems ambivalent; she's relieved and disappointed at the same time.
Sym sets off to find Victor. He seems to be in good spirits.
As they walk back to camp, they hear an explosion. It's the plane. Oh dear.
One of the passengers, a journalist, was killed in the explosion. We were never even told his name, so R.I.P. nameless guy.
No one knows exactly what happened. Understandably, people are upset; one woman even faints twice. The only person who seems okay is Victor. He decides to make everyone some tea.
A few hours later, everyone's asleep. Sym decides they're exhausted from all the fear, though she also notes all the empty teacups by each sleeping traveler. Interesting.
Sym feels afraid, but she's not sure why. She confident they'll be rescued. She's just afraid.
As she tries to get some sleep, she has a quick conversation with Titus: Sym wants to know if he ever worried he would die. He doesn't answer.
Sym is interrupted by a masked man. It's Victor, in a special facemask designed for blizzards. He says it's time to leave for Symmes's Hole.
