Hi Omegaverse knower here and just as a heads ups don't abbreviate it as a/b/o without the slashes since that's a slur against the aboriginal people!!! Very important Omegaverse etiquette to know before talking about it.

Anyway Swiss acts more like the Omega than TC does so the chart is probably just wishful thinking (and knowing Swiss a bit better now, a really outdated way of relationship dynamics)
