Do we know for sure that Adah is invisible to Dehane? All we know is that she is invisible to Dumuzi — and that by Dumuzi’s testimony. I keep going back to Justin’s comment that he trusts Dumuzi “as far as I can throw the Wells Hotel” after he eavesdropped on Dumuzi and Miko (Old World, #3896/2018-10-29).
Seems to me the way to handle the thing is getting the local Tower to upload its consciousness. Which could put Adah at risk for uploading with it if she has proximity when it happens.
Here’s a link to the start of that scene:
