Not a lot of help being given here.
1) The highlighted phrase is in English (2 words on separate rows).
2) Letter changes for the 3rd character affect both rows (the following 3 letter changes complete the 2nd word).
The way the 3rd character addresses one of the other characters is what's 'inappropriate' this time (if this is too much help, I'm sorry - but it's better than nothing, I think).
