I’m not his bodyguard,” said Isabelle. “I’m his girlfriend. Which gives me the right to kick your ass if you bother him. That’s how it works.

WHY DOES THIS KEEP HAPPENING?" There was a sound of shattering glass, and they both sat up to see Alec glaring at them. He had dropped the empty bottle of wine he had been carrying, and there were bits of sparkly glass all over the cave floor. "WHY CAN'T YOU GO SOMEWHERE ELSE TO DO THESE HORRIBLE THINGS? MY EYES."

"It's a demon realm, Alec," Isabelle said. "There's nowhere for us to go."

"And you said I should look after her-" Simon began, then realized that would not be a productive line of conversation, and shut up.

Izzy," said Jace, as they neared the pond, and she jumped up and spun around. Her smile was dazzling.
"Jace!" She flew at him and hugged him. Now that was the way sisters were supposed to act, Clary thought. Not all stiff and weird and peculiar, but happy and loving. Watching Jace hug Isabelle, she tried to school her features into a happy and loving expression.
"Are you all right?" Simon asked, with some concern. "Your eyes are crossing."
"I'm fine." Clary abandoned the attempt.
"Are you sure? You looked sort of… contorted.

I've noticed the Fair Folk often say 'perhaps' when there is a truth they want to hide," Clary said. "It keeps you from having to give a straight answer."
"Perhaps so," said the Queen with an amused smile.
"'Mayhap' is a good word too," Alec suggested.
"Also 'perchance,'" Izzy said.
"I see nothing wrong with 'maybe'," said Simon. "A little modern, but the gist of the idea comes across.

It doesn't hurt."
"But my eyes do," said a coolly amused voice from the doorway. Jace. He had come in so quietly that even Simon hadn't heard him; closing the door behind him, he grinned as Isabelle pulled Simon's shirt down. "Molesting the vampire while he's too weak to fight back, Iz?" he asked. "I'm pretty sure that violates at least one of the Accords."
"I'm just showing him where he got stabbed," Isabelle protested, but she scooted back to her chair with a certain amount of haste.

I am here to determine my relationship."
Simon goggled. She couldn't be talking about him. Could she?
"Do you see that man?" Isabelle asked, pointing at Simon. Apparently she was talking about him. "That's Simon Lewis, and he is my boyfriend. So if any of you think about trying to hurt him because he's a mundie or--may the Angel have mercy on your soul--pursuing him romantically, I will come after you, I will hunt you down and I will crush you to powder.
