Every decision you make, makes you. Never let other people choose who you’re going to be.

We live forever by the grace of human love, which rocked strange children in their cradles and did not despair and did not turn away.

Simon: I love you Isabelle Lightwood! I love you and I will not go away until you tell me you love me too!

Isabelle: Take your clothes and go!

Simon: Isabelle! Stop throwing clothes at me! Just because your a Shadowhunter and I'm a vampire doesn't mean we can never happen. Our love is forbidden like the love of a shark and a-a sharkhunter! But that's what makes it special!

Isabelle: Oh? Which one of us is the shark, Simon? Which one of us is the shark?

Robert Lightwood: What is going on? Why are you yelling outside my house?

One for sorrow, two for mirth, three for a wedding, four for a birth, five for silver, six for gold, seven for a secret that's never been told.
~ Simon
