Summary:

Magnus let out a hollow laugh that almost sounded like a bark. “I’m the High Warlock of Brooklyn, Alexander. I know how to take care of myself.”

Despite his apparent cold and arrogant tone, there was a sadness in his voice as well. Sadness mixed with a hidden fondness that didn’t match the rest of his feelings at all. It was barely recognizable and somehow still glaringly obvious.

Summary:

Alec’s not sure how to process that Max, his five-month old baby, is apparently a dimension hopping private investigator 140 years in the future. Magnus has a much easier time dealing with it.

“Sorry,” says Max, blinking rapidly. He doesn’t look away from Alec. He looks – Alec doesn’t know how to describe the expression on Max’s face. “It’s just… it’s been a long time since I saw you, Dad.”

Summary:

“Are there any side effects? Of dimension-hopping?”

“It depends,” said Magnus. “Some travelers say so. Not many shadowhunters have made the trip, though. Are you experiencing something in particular?”

“No,” Alec lied.

Ever since Jace went through the seelie portal, Alec has been having dreams—visions of parallel worlds like that one. Lydia is hatching a plan, Magnus is sharing poetry, the Lightwood siblings are working on talking things out. And in light of these alternate lives, Alec considers his choices in this one.

Summary:

Alec has enough on his plate right now. His parents are furious at him, Magnus Bane is making him feel things he’s trying so hard not to feel, his wedding is coming up, and his world is breaking apart.

What he doesn’t need is a fussy mundane version on himself showing up in the Institute basement. What he doesn’t need is Magnus telling him that they’ll just have to wait for Seelie Magic to suck that version of himself back to his own dimension.

But since when does Alec get what he needs?

Alternate Dimension Alec gets trapped in the Shadowhunter reality at some point after the “I know you feel what I feel” scene. The gang desperately tries to stop chaos from ensuing.
