Answer:
I believe the answer is: "The report is due on Friday, so
WE"LL have to decide on a topic soon or WE will never finish," Nick said to Sara. Although Sara agreed with HIM, SHE was not nervous about getting the report done.
Step-by-step explanation:
We'll refers to both Nick and Sara It makes sense in these sentences because Nick is addressing both Him and Sara. Next up is "we" because it is grammatically correct and still refers and emphasizes that Nick is talking about him and Sara. As far as I know, Nick is a boy name and Sara is a girl name so referring to Sara as a girl and Nick as a boy makes sense.
