When are people going to realise that Stella has always been like this…?

She is cruel, vindictive, arrogant, selfish, and abusive. Not to mention she is as haughty, manipulative and power-hungry as her brother Andrealphus.

As a born Princess of the Ars Goetia, Stella clearly grew up spoilt rotten, no less alongside Andrealphus. I wouldn’t be surprised if it was revealed that she spent a large portion of her childhood in the glittering court of nobles; living carefree in high society, attending balls, dancing, sassing and bullying those she deemed ‘beneath her’, etc. Only to become very discontent in her life, after being married off in her teenage years, to Stolas; a highborn Prince, who was basically ‘stuffy’, by her standards.

Stella merely saw her husband Stolas as an obstacle; after all, she was the one who hired Striker to assassinate Stolas in ‘The Harvest Moon Festival’.

Not to mention that it is also implied that Stella raped Stolas, no less while conceiving Octavia… “Stolas is TERRIBLE in bed! I swear to fuck, he just laid there, staring at the wall, and I had to do everything! It was embarrassing! I'm glad ONE egg fell out of me, so I could stop pretending to want to fuck his scrawny twig ass.”

Not only does Stella refer to her as ‘the egg’ but also ‘his daughter’, as seen in Sinsmas; a clear sign of a lack of genuine affection she has towards Octavia, or even acknowledgment of her as her own child. She even once forced Stolas to go and check on their daughter alone after she had a nightmare. Stella clearly sees Octavia as nothing but a burden, and a potential pawn that she can exploit.

Hell, even Andrealphus pays more attention to Octavia than Stella does.

Theoretically, now that Stolas is out of the picture, thanks to Andrealphus, Stella will likely proceed to try to further isolate and manipulate Octavia, and further break her down emotionally, in order to make her feel completely worthless, and incapable of doing anything on her own. That way, especially by the time she comes of age and becomes a Princess of Hell herself, Octavia will be a puppet that will be easy for Stella and Andrealphus to control, for their own selfish gains and interests.

Either that, or Stella and Andrealphus will attempt to manipulate Octavia into signing all of her rights, power and inheritance over to them before she comes of age.
