There’s no walking back. My initial post said: “used Sky from the beginning” If they had released Sky’s voice publicly before contacting Scarlet it would have been a different situation, but they made the decision afterwards.

Simply recording Sky’s voice beforehand doesn’t imply a different intent. This isn’t animation where you’re trying to match two mediums and you want the actors recording first. Having a similar voice to work with would have been useful internally to know if they wanted to pay what it might cost to use her voice.
