That is probably the most natural statement for Finn to make, it just sounds a bit weird to me as it is implemented now. ‘It’s the First Order, they’ve fOUNd us!’ - with the middle part of ‘found’ sounding like it is slightly too highly pitched. Again, not a sound person, just noting what sounds weird to me.
I’m not a sound engineer either but I agree. If the sound clip for that line is available, I could take it for a spin in Audacity or Ableton Live and see what I could muster up. “Found” needs to be teeny-tiny bit slower and “OUN” balanced.
Tbh, I don’t have that much faith in myself but just trying to be useful for once, LOL! 😄
