She doesn't hate the queen, nor dislike her. Her sadness and pity for the torment Queen Helaena had experienced, a grief shared with the king, and most of the realm and Keep itself. Gannica's actions come from a place of self-interest and self-serving instincts. When even the whisper of an opportunity tickles her ears, she tucks it away for the most strategic time to strike. Like a blacksmith crafting a blade, or a hunter aiming his bow. Lady Gannica wasn't raised like this; it's in her blood. So, when she brushes her hand against his, stares a little longer than proper, and conjures forth that delighted sparkle in her eyes, it's not because she dislikes the queen... it's because she loves herself.
It has been a slow game, thus far, save for her manoeuvring her father and her House out of unwanted attention when he foolishly tried to declare for Rhaenyra. Balancing herself between the Queen Mother, the king's grandsire, the pious nature of the Faith, brimming war tensions, and the hawkish eyes always on the king himself, whether he seemed to want it or not — Gannica has been presented with very few true opportunities. She has been patient, cautious, and eager. "It is not about what I 'want', Your Grace," Gannica replies, her voice coaxed into a soft but unyielding tone, drawing her breath intentionally into her upper chest and allowing her breasts to strain against her gown. "— it is what I need," she repeats the word with a small shiver born of the thrill of her chase drawing a fraction closer to her goal, "to want is such a trivial thing... but needing something? Need consumes a person," she curls her fingers to brush against Aegon's hand where it grasps her wrist, "as thoughts of you have consumed me."
She won't deny his accusations; she's too smart to make the mistake of thinking Aegon would believe she has no interest in power, in a crown — Gannica is drawn to it like a moth to a flame. The only person in the world who knows the true extent of her obsessive desire for power is Gannicus; some may see glimpses of her nature, but only her twin knows the full depth. She doesn't play the wallflower when Aegon bears down on her a little more, a little closer, his breath on her skin... she subtly shifts her body, her stance, the tilt of her head, all to invite him in. "I know what I am asking for." Gannica twists her hand in the king's grip, pulling it to settle on her waist with a smile mostly hidden from view, the cool metal of his rings contrasting the warmth of his skin. "Let me offer my company, Your Grace; my body against yours, your hands on my skin," she all but purrs into his ear, her voice thick with desire and promise, "the nights grow long, and I am so deeply gripped by a need for my king."
