Really, the signal to summon a minion doesn't need to be anything fancy or difficult. It's essentially a subtle sort of 'hey, you, c'mere.' (He just liked to scream for Pain and Panic because it was what worked best when they were within earshot.)

He realizes after he's done signalling for Alice that he started just after Renee started talking.

"... You're the one who sees." It's totally not a question.

As far as what Anne's watching? It's quiet, in its way. As though this is what has always wanted to be here, even if it's... not, quite. It's what needs to be here now, now that all this has happened and somewhere needs to be this way. It's divine and mutable and as though it has always been, even if the changes haven't yet crept across the big room yet, much less into any of the other caves.

They'll get there.
