Quote #7
"Don't you think marriage is the one single thing we should all hope for most in life? Doesn't it make you more whole than living alone? […] I think it does. Marriage is like a third person," Lili said. (9.75, 9.77)
Or fourth person, if you count Einar, Greta, marriage, and Lili.
Quote #8
"This is a special wedding. I see something special here. In ten years the two of you will be extraordinary people." (11.19)
This is a brief flashback to Einar and Greta's wedding day. But it's not like anyone ever says, "These two boring people will still be boring married people forever," though, so as far as foreshadowing goes, it's pretty vague.
Quote #9
Part of Greta wanted to be married to the most scandalous man in the world. It had always annoyed her when people assumed that just because she had married she was now seeking a conventional life. (12.15)
Greta married Teddy partially because her parents would hate it. That's another reason she considers staying with Lili even though Lili is no longer her husband—they still live together like spouses because Greta likes to go against the norm.
