I can for you, since it’d be such a simple job.
Would you rather they be hard-coded? Since most people are going to watch via Google Drive, and there are no foreign language options anyway, I’d think that would be best.

If you can send me the relevant shots or scene, I can add subtitles for those two lines formatted like the OT or PT, whichever you like.

TCW doesn’t ever have subtitles for alien dialogue, does it? I imagine the closest thing to be faithful to would be the subtitles in TPM and AOTC.
