Her arms slide through Aggie suddenly, but at least the rope -- the noose -- has fallen away, and Blue stumbles back. "No," she says "no, it's not okay," realizing what has happened. Or at least, a little of what has happened. There's a part of her that's latched onto the noose, like some woodcutting or black and white picture of the worst parts of history, but come to horrible life because it was her life. Despite the ridiculousness of focusing on that when Agatha has turned into some all-powerful terrified-angry energy being in front of her, it's where her mind is stuck.

The wind tears at her hair, freed from its clips, and lightning cracks across the sky. She says, "What they did to you, they can never make that right, no one can. But they're not here, Aggie."

Blue tries to think of what it had felt like, holding Magnus' hand, the night of the earthquake. It's not something she'd ever want to repeat, but what Aggie looks like now -- it looks like some visual representation of the power she'd felt flooding through them both when Magnus had nearly killed Alec. When she had nearly killed Alec.

She doesn't want Aggie to be responsible for something like that. Not after everything she's been through.

If she can siphon that off, just a little, maybe... Be a mirror in a mirror.
