I choose to believe they're watching the emergency medicine scene from The Martian. Now you may be wondering how people from an alternate history early 1900s New York are watching a movie from 2016 set in 2035 based on a space race that never started in the Avatar universe.

To which i respond that stranger things have happened in the Avatar franchise. Like letting someone from that Shyamalan abomination become the voice for a major recurring character.
