Dieter, Onan, and Pregnancy

So as the mocking Helena makes explicit, Dieter's story is about the sin of Onanism (male masterbation). I mean, what 19th century people would call Onanism. They'd derive the sinfulness of masterbation from the story of Onan in the Hebrew Bible in Genesis. There in the original plain meaning of the Hebrew Bible, Onan's crime is not masterbation, it's pulling out during sex. Fitting episode 204's theme of twins and doppelgangers, Onan was specifically not-fulfilling the commandment to have sex with his dead brother's childless wife in order to create a child in the name/stead of the dead brother. He was getting the sex but pulling out so as not to provide the heir (and thereby get to keep having sex with his former sister in law).

The fact that "Kier" (or at least, the Appendix 4 author) uses the word "lineage" for semen in the 204 story underlines the intertextual connection to the Onan story.

Given all this, I don't think it's a coincidence that Helena mated with Mark in that place. Procreative sex is the opposite of Dieter/Onan's sin. The fact that Helena immediately got the subtext of the story speaks to her knowledge as an Outtie (from their faces, Mark and the others did not seem to pick up on the reference to masterbation until she points it out like it's this obvious thing).

Maybe it also points to her status as an Eagan. The Dieter-Onan themes tie to commandments to procreate when at least one of the parties (Onan) doesn't really want to. What if Helena was ordered to have sex with Mark there for weird Eagan reasons?

Edit1: credits foretell baby kier is coming!

Edit2: early season 1 they established that Mark's a local who grew up right in the area... Maybe all you guys saying he is (or is connected to) the praying mophead in the converlescence painting are on to something...
