SPOILERS for Unend Season 2, Episode 7: Flashback and Season 1, Episode 18: Homeward
The scene between Artifice and Dot in Homeward was striking for many reasons, but I want to focus on the characterization of Dot that we get from it.
You remember well, I think, how, when confronted about their lies by Artifice, Dot completely falls apart. The situation would have supported many reactions, embarrassment or defensiveness for example, but instead, Dot begs for mercy. They obviously experience acute terror, a dread that, when looked at from a little distance, like us listeners do, seems a little unwarranted.
Sure, there was some ominous forshadowing, Cleo's conversation with Artifice and Dot's own dark thoughts about their destiny. However, whatever apprehension the listeners or Dot might have felt is instantly deconstructed by Artifice. He reassures Dot: They are in no danger. The Grandmothers know. Realization will find them, it is inevitable.
Where does that leave us with Dot's characterization, then? They seem to have a deep fear of failure, something that is indeed discussed by Artifice and Dot immediately after. They are anxious to an unhealthy degree, something we already know, having been privy to their private little panic attacks before.
Then Flashback rolls around and neatly recontextualizes this whole interpretation.
Dot lost their entire family to an epidemic. They were robbed of their whole support system, of everything physical and emotional a child needs to survive. They were saved by the Mothers who, purposefully or not, took on that responsability. They attached to the Mothers for support and for purpose in life.
And now, Dot is failing to become a true part of the Order, a true part of the family. They do not have what it takes to be a Mother. That does not merely mean failing to obtain power or even taking on a profession. To Dot, failing to become a Mother means loosing everything, as they know can and will happen, because it has happened before. They have experienced that terror, they have lived through it. When they begged with Artifice in Homeward, they begged for their life.
It is not real, of course, there is no harm coming Dot's way for failing to find Realization (I am eighty percent sure). But it feels real to them, not in expectation, but in memory. Dot's fear of failure now reads much more like a symptom of their fear of abandonment and their anxiety more like a response to trauma than to overstimulation.
What excites me about this are the story opportunities this opens up for Dot's relationship with Cleo. Before, I was torn over where this story would go. I could see both scenarios as conclusions to Dot's character arc, Mother Anxiety as well as DotCleo, with the caveat that ending up with Cleo would mean Dot had failed in overcoming their anxiety.
Now, there is great potential for the realization (!!) that belonging can be found elsewhere and that failing to become a Mother does not mean total abandonment. Being with Cleo now would mean that Dot had succeeded in overcoming their trauma.
Also: Is there an official ship name for Cleo and Dot?
Edit: Changed the shipname. Thanks, hello-eeveev!
