“The missing stairs baffled Clary. What did vampires have against stairs?
-Clary, pg.266”

“Oh, come on," Clary said. "You're a vampire, not Spider-Man.”

“Simon kept pace beside Clary for a few moments without speaking before he said, “So what did I miss? Naked dancing ladies?”
Clary thought of the male faerie‘s torn-open ribs and shuddered. “Nothing that pleasant.”

“It doesn’t change what we are to each other. It’s like there’s always been a piece of my soul missing, and it’s inside you, Clary.”

“Halfway down the stairs
Is a stair
Where I sit.
There isn't any
Other stair
Quite like
It.
I'm not at the bottom,
I'm not at the top;
So this is the stair
Where
I always
Stop.

Halfway up the stairs
Isn't up,
Isn't down.
It isn't in the nursery,
It isn't in the town.
And all sorts of funny thoughts
Run round my head:
"It isn't really
Anywhere!
It's somewhere else
Instead!"”

“Perhaps it was right to dissemble your love,
But—why did you kick me down stairs?”

“Belatedly, Clary recalled something. "I thought you guys said onlyof the vampire bikes could fly?"… [Jace:]"Only some of them can!" "How did you know this was one of them?" "I didn't!" he shouted gleefully…”

“Tessa put a hand against the wall as she made her way numbly down the stairs. What had she almost done? What had she nearly told Will?”

“In the oldest, bunched houses with tottering stairs”

“The elevator to success is out of order. You'll have to use the stairs… one step at a time.”
