Jeesh... Overthinkers! Where did good old simplicity went? I am sure Rowan is capable enough to not use some spell-crutch. Just put Jezera on a leash and fuck her into submission! She is the one who likes to overbuild and overthink, so dominating her through simpler means would be a perfect mockery of her ways.
And lets be honest, we all gathered here in "Dominate Jezera" camp because we want more than just to dom her. We want to see her humiliated, destroyed, want to wipe the smugness off her face, to prove to her that she and her ways suck.
So, no sophistication. Sophisticated means would prove to her that her ways, at least in principle, work. That she wasn't wrong with her life choices, that she has no need to regret them. She can even view Rowan as a pupil of sorts - and the one who beat her her own game, a source of pride! But we want to make her regret, aren't we? We want to break her pride, right?
So, it must be something simple, something brutish even.
