No person on earth pisses her off more than Adam, but she also hates herself from being attracted to him.
She knows this toxic attraction she had towards Adam is not healthy, and it will lead to a very destructive path, but she can't stop herself.
Seeing his smug smile on his face makes her want to punch him, but she can't because Adam will stop her just like he did a few seconds ago.
Now with her wrists in his hand, he has control over her. She feels powerless, unable to pull her hand away from him.
But then he adds more salt to the injury by blatantly questioning her why she is angry, even though it can't be any more obvious.
She saw him walk out of the guest room where she found Natasha is such a state that would put most women to shame.
What Adam did to Natasha made Julia furious, not only because she is her friend, but also because he, too, hates Natasha's guts.
