"Neither do you," Luke responds gently, looking over at Alec for a moment before he glances back out at the party. Magnus is here, inevitably leaving glitter everywhere and Luke is certain he's going to be finding it in his hair and in between couch cushions for weeks, but as much as he might consider the two of them friends, he knows who Magnus is really here for. There's no doubt in his mind that the warlock does most of what he does with Alec in mind in some small way.

"You have me and you have Spencer," he points out. They're not Alec's family, they'll never be able to take the place of Isabelle or Jace, and he's well aware of that. He isn't trying to fill in for people who are missing, but offer something else Alec might not even be aware he'd like to have around. "And Magnus, of course."

Darrow does that for people, he's noticed. It gives them different worlds, different friends, even different families. People who might not have looked twice at each other become friends and everyone ekes out a place where they belong.
