Andrealphus & Stella

Fittingly enough big brother Andrealphus is the Blue Oni to Stella's Red (and not just because of the ice theming). While she's quick to anger and go for the blunter, curler assassination, Andrealphus is the one to remind her of the bigger picture, instructing her to be patient, take in all the details and then strike, rather than kill Stolas, as all that would do is transfer all his owning to Octavia.
