“So you're trying to make her happy despite the fact that the reason she's unhappy in the first place is you," said Simon, not very kindly. "That seems contradictory, doesn't it?"
"Love is a contradiction," said Jace.”

“It's not funny, Jace," Alec interrupted, starting to his feet. "Are you just going to let her stand there and call me names?"

"Yes," Jace said kindly. "It'll do you good-- try to think of it as endurance training.”

“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.”

“She said I'd better not make her unhappy because I oughta know that she's never unhappy alone.”

“"Or maybe she's trying to take the attention off you," Simon said, almost absently. "You know since your parents don't know you're gay and all."
Alec stopped in the middle of the road so suddenly that Simon almost crashed into him. "No," he said, "but apparently everyone else does."”

“Baby?"
She perched beside him in the chair. "You're kidding me right?"
"I was trying it out, no?"
"no," she said firmly
Simon & Clary”

“You really love her don't you," she said.
With all my heart."
She looked as sad as I'd ever seen her.
What's your heart telling you to do?"
I don't know."
Maybe", she said gently,"You're trying to hard to hear it.”

“Clary?” Jace tilted his head to the side, studying her face. “You do—you still love me, don’t you?”

“I love Jace Lightwood,” she said. “I don’t know who you are.”

“Is there some particular reason that you're here?"…
"Not this again."
"Not what again?" said Clary.
"Every time I annoy him, he retreats into his No Mundanes Allowed tree house." Simon pointed at Jace.”

“There is no pretending", Jace said with absolute clarity."I love you, and I will love you until I die, and if there's a life after that, I'll love you then."
She caught her breath. He had said it-the words there was no going back from.”
