Shadowhunters Season 2 Episode 20 Quotes

Jace: How could you side with him?
Malakai: There's only one side...the side of the angels. Valentine is only doing what the Clave has been trying to accomplish for centuries: eradicate demons.
Clary: No! No, the angels would never be in favor of killing millions of innocent Downworlders along with demons.
Malakai: When Razeal created the first Shadowhunter, there was no such thing as Downworlders. But over the centuries, disgusting half-breeds emerged. Warlocks, vampires, Seelies, werewolves...they banded together and grew more powerful. Finally they will be destroyed...and so will you.

Seelie Queen: Simon is quite valiant and chivalrous, unlike any of the other night children I've come to known. You're all free to leave. My servant will escort you out of the court to safety.
[She reveals a glowing orb]
Luke: What's the catch?
Seelie Queen: What makes you think there is one?
Simon: Luke, let's just go.
Luke: Nothing ever comes for free. You never do anything out of the kindness of your heart. Hell, you were gonna sell the entire Downworld...
Maia: Let's just get out of here while we still can.
Seelie Queen: She's a smart one, you should listen to her. Before I change my mind.
