Clea’s Hauler. This is the one axon that stands out from the rest:



1. The in canvas version differs significantly from the portrait version in Renoir’s atelier.
2. The only Axon not featured on the manor atelier’s ceiling.



It’s a given Clea hates her Axon, which might explain both 1 and 2. But what’s interesting to me is the original portrait version of the Axon, and why the canvas version looked so different. 



We know each Axon is supposed to represent Renoir’s perception of his family members, and all except Clea’s appears to have a matching (Sirene) or ambiguous (Visage, Reacher) gender. The original Hauler however is quite masculine (if it’s meant to be feminine, then it’s not flattering), so makes one speculate what Renoir sees in his eldest:



We know she follows her father’s fascination for the morbid (both design Nevrons), has a penchant for violence (devised the Gauntlet and devoted to fighting the Writers), and is considered unconventional in that era: being near 30 and unmarried. 



Whatever Renoir tried to imply about Clea’s personhood, even if he didn’t see it negatively (just “see things as they are”), obviously ticked off Clea so much she didn’t want him repaint it on his ceiling - even if it’s his way of glorifying his family. Renoir must’ve thought he could amend it by portraying the new Hauler closer to Clea’s appearance, but he clearly missed the point. 

The weird thing about one particular Axon
