Alec Lightwood: What is all that?

Magnus Bane: Each of those belonged to someone I loved and outlived. A different committed relationship for each one.

Alec Lightwood: Why do you keep it?

Magnus Bane: I may be magical, but my memory's far from it. I keep those mementos to remember them by. Look, Alec, you know my history. I've always been honest with you about that.

Alec Lightwood: Well... Now that I've seen some of that history with my own eyes, I can't help but think... if I'm lucky, maybe one of my arrowheads ends up in that box.

Magnus Bane: Look, I don't even want to think about you being gone...

Alec Lightwood: But one day I will be. And you'll just, move on...

Magnus Bane: I'm immortal! It's not as if I have a choice! I can't change what I am, and neither can you! Look... can we just stay in the here and now? Hmm? Look, I want to cherish this moment... with the one I love.

Alec Lightwood: You're right. I love you, too.
