See title. This will eventually be divided up by quest (Main, Chloe's, etc.) as well as extras (skits, end-of-battle poses, etc.), but that involves me actually tracking down all her in-game scenes first. :D;;
Each non-skit scene has the runtime in minutes and seconds listed beside it. Grune rarely says more than a sentence or two in a row, and so this ought to prevent people for looking for more speech where none exists!
Major spoilers about Grune are marked. Anything in the Grune's Quest section when it exists can be considered a spoiler by default, so tread carefully!
