You can hear what I assume is Ahsoka in the background of his second line. I might just go with another voice clip for that, but if you can find a way to mask or get rid of her voice, go for it. The voice lines could probably use some sort of ‘robot’ filter to make it sound more like it’s coming from Grievous. And Grievous’ grunts and laughs should probably be dubbed over. But other than that, I do think those voice lines fit very well.
Yes yes and yes. I’ll remove the background sounds and everything but I’m going to tweak the dialogue anyway.
EDIT: Almost all of those lines are scrapped or repurposed, I may upload a clip in the future but don’t expect me to anytime soon.
