Arkady: Do you know what that was, Luke? That was exactly one second of my overdose experience when we were fifteen. If you ever do something like this again, I am going to give you five minutes of that.
Cloud Cuckoo Lander: Justified by a prior possibly-fatal drug overdose experience. A later near-death by drowning seems to have restored her to her senses.
Crazy Survivalist: Is displeased with Sirkka when she gets pissed with him over the gun he kept in her house without telling her.
Hypocrite: Upset with Sirkka over her polyamory and her spiritualistic justification for it... but doesn't consider sleeping with various other people to be unfaithful to her, nor does he think not telling her about it dishonest. Uh, sure.
I Want My Beloved to Be Happy: Jack is in love with Sirkka and doesn't approve of her polyamorous ways, but rather than object, he just stays away from her. This makes Sirkka, who loves him back, miserable.
Really Gets Around: "Is there anyone Jack hasn't slept with?" And the aforementioned incident with Connor's mom.
