I'll ask. Kat! Why are you so happy today? It's quite funny to see you on this kind of a roll and I'm  curious now.

Oh it will be. Because, as we know, Billie is nothing if not honest.

He probably will. Because I'm sure he'll notice it in Alex before Alex even does it, simply since they're having a conversation.

I had a feeling you would understand Dahl's thing, and I'm sure once she's feeling better, Dahl will be alright with her too.

Sal: it's a blue-green color. It's a really soft tone to everyone else, but I see it very well. It's very pretty. I think Clary would see it about how I do too.

Hmm... you know, maybe it would work on him, so long as his subconscious didn't go hyper vigilant on her again.  But he likes her aura and she helped him so he won't have an issue with her.

That makes a lot of sense. Like I could see if she were ever demonstrating, Billie would just look at everyone and then at Kat like, 'I feel like I'm missing something. Why am I feeling like that?'
