Hieron wards and ritual protection
The Hieron has more than an alarm on the door. Its wards make approaching with ill intent physically sickening. That gives Diana a way to judge a visitor before believing what they say. There is a limit, though. Diana thinks a witch as powerful as Zatanna could break through them; Zatanna answers that she could not do it quietly. So this is a protective boundary with warning signs, not an absolutely impenetrable fortress. When Zatanna arrives, the Hieron identifies an unknown presence. Her ability to stand inside without tearing the place apart becomes evidence that she is not there to hurt Diana.
Fighting another witch: words, hands and water
Diana's fight with Zatanna makes the practical side of magic pretty clear. Cutting off someone's voice can shut down spoken spells, but it does not necessarily shut down the witch. Zatanna casts using her fingers while Diana has her in a chokehold, phases out, and gets free. Diana adjusts. When she traps Zatanna in water, she makes a point of preventing both speech and signing.
That water trap comes through the trident. Diana calls to it mentally, gets an answer, and turns Zatanna's water attack into a column that closes around her. The trident responds again when Diana tells it to release her. That matters because it is not just a metal spear which happens to shoot water. There is a presence there that hears Diana and answers her.
Troika: what goes into it, what using it does
Troika is made with Scylla's blood, Cerberus's fur and the sacred icy tears of Styx, then blessed by Hecate. That last connection matters: Hecate is tied to magic, death and the crossroads. The lasso takes that crossroads idea and makes someone face the truth of the choice that has trapped them.
Against Giovanni Zatara, Diana does not simply ask questions until he admits something. She binds him and invokes Hecate, Scylla, Cerberus and Styx. The scene moves into a blue inner space where the roads of the lasso lead to Sindella and to Zatanna as a baby. Giovanni thinks he is being asked to choose between wife and daughter. The answer is that the choice was already made. His guilt has left him vulnerable to others shaping the reality he experiences. To get free, he needs to face what happened rather than remain inside that moment.
But the person holding Troika is not safely outside all of this. Diana knows her own conflicted state of mind makes using it dangerous. Zatanna touches the lasso, calls to her father and reaches him, then pulls him out. Breaking that connection leaves Diana trapped at her own crossroads, alive but unresponsive outside. Calling to her as Zatanna does not work. Zatanna uses the Circe Stone to identify Diana's mother, breaks it and changes her appearance into Circe. Diana responds to the person she believes is her mother and takes her hand. That gets her out, but Diana explicitly knows she has failed with Troika and that consequences are coming. At that moment she cannot see what those consequences are. That is not a clean, cost-free win.
Aphrodite's gift is not just a personality trait
Aphrodite's gift has an uncomfortable edge. She tells Circe that she gave Diana a little of the power that draws others toward her, enough to help people join Diana's side and her causes. Circe immediately sees the problem: how can Diana know whether someone's love was freely given? Aphrodite has felt her own power working back on her through Diana, which is why she says she can no longer keep visiting the island. She trusts Diana not to abuse it, but regrets the loneliness and uncertainty it can create. That is a divine influence attached to Diana, not a spell she has to speak every time she wants somebody to like her. It also does not prove that every relationship in the book is false or that nobody can resist her.
