Audio problem: Murph's dialogue doesn't sync with her mouth at the lines "you hate farming, Dad." (00:17:43)
Audio problem: Tom's wife coughs into her sleeve as the shot changes; when it switches to Murph's boyfriend, you can see her reflection in the window and she is not coughing. "How long have you had that cough?" he asks, and although she replies "A while," you can see in the reflection that she was originally filmed coughing again as a reply. (01:49:20)
Answer: Cooper would have already met his other family members (grandchildren and great-grandchildren) when they first arrived at the space station and before going in to see the frail Murph, who made the trip while in-stasis. Because she is so frail, everyone would discuss beforehand how the meeting should proceed. Also, it is already a long-running movie, and adding an extended "meet and greet" scene would drag out the ending and lessen the emotional reunion between Cooper and Murph.
