I Guess It’s a Lightwood Thing…

Isabelle: Simon’s a rat.
Alec:Did he touch you? If he tried anything-
Isabelle: Not like that. He’s a rat.
Jace: She’s drunk
Isabelle: That’s not the point. The point is, Simon drank one of those blue drinks-I told him not to, but he didn’t listen-and he turned into a rat
:
Gabriel: Father is a worm
Gideon: What do you mean, Gabriel? What did Father do?
Gabriel: He’s a worm
Gideon: I know. He has brought shame on the name of Lightwood. But we need not be like him
Gabriel: You’re not listening to me. He’s a worm. A bloody great serpent like thing.
