“Well, I’m not kissing the mundane," said Jace. "I’d rather stay down here and rot."
"Forever?" said Simon. "Forever’s an awfully long time."
Jace raised his eyebrows. "I knew it," he said. "You want to kiss me, don’t you?”

“The descent into hell is easy." said Alec. "You just said kiss the cook" "Dammit" said Simon. "I knew Jace was screwing with me”

“Basia coquum," Simon said. "Or whatever their motto is."
"It's 'Descensus Averno facilis est.' 'The descent into hell is easy," said Alec. "You just said "Kiss the cook."
"Dammit," said Simon. "I knew Jace was screwing with me.”

“I’m not going to kiss you,” Simon said. “Ever.”

“I’ve never heard anyone say that before,” Jace mused. “It was a unique experience.”

“So, technically," Simon said, "even though Jace isn't actually related to you, you have kissed your brother.”

“Come on guys, you cant fight like this forever"
"Actually," Simon said, raising his hand,"I can".
Jace made a weird noise and I realized he was trying not to laugh-which by the way, wasn't working.”

“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.”

“Fresh is better. But you've never drunk fresh blood. Have you?"
Simon raised his eyebrow in response.
"Well, aside from mine of course," Jace said. "And I'm pretty sure my blood is fan-tastic.”

“Jace slammed his hand down on the stele. “Clary-“
“She said she doesn’t want it,” said Simon. “Ha-ha.”
“Ha-ha?” Jace looked incredulous. “That’s your comeback?”

“Well, I hate to tell you this," she said, "but your friend is an asshole."
"He's not my friend," said Simon. "And I couldn't agree with you more, actually."
