In Fear Street Part One: 1994, C. Berman is portrayed as a young adult, likely in her early 30s. Although the specific age of the character is not explicitly mentioned in the film, we can make an estimation based on the timeline and context.
In the movie, C. Berman is shown as a survivor of the events that took place in Shadyside, which occurred in 1978 and 1994. In 1978, she is a teenager attending Camp Nightwing, so it can be assumed that she is in her mid-teens during that time. Fast forwarding to 1994, the present-day setting of the film, we see her as an adult who has been deeply affected by the horrors of her past.
Considering the approximate 16-year gap between the two time periods, we can infer that C. Berman would be around her early 30s in Fear Street Part One: 1994. This estimation aligns with the portrayal of the character in the movie, where she is depicted as an adult dealing with the trauma and aftermath of the events that unfolded during her teenage years.
It’s worth noting that the age of a character can sometimes be open to interpretation, as films may not always explicitly state their ages. However, based on the information provided in Fear Street Part One: 1994, it is reasonable to assume that C. Berman is in her early 30s during the events of the film.
Please note that my response is based on the information available in the film and may not reflect any additional details or changes that may occur in the Fear Street book series or subsequent films.
