Eunice Wong not in the credits as the hitchhiker.

I just watched the film on Showtime. At the end, the main character Natalie played by Shayla Beesley is driving away in a truck and stops to pick up an young Asian woman in shorts. She is credited as the Hitchhiker and was named Eunice Wong. But she is not in the credits of the IMDB and not mentioned anywhere online. Was she a last minute addition that was only available on video?
