s23e03 — A Grain of Truth

I have a lot of questions about the age of the characters and actors. The drowned boy was 17 years old, i.e. Chrissy is also 15-17, so in the present she is 35-37? The actress doesn't seem to be even 30. The gray-haired man who defended Chrissy looks like he's under 60, in the past he and the girl look the same age (well, or he's 20 years old), and in the present he's 20+ years older. To be honest, it made it very difficult to comprehend the plot.

It looks like the defender led a riotous lifestyle. Poorly preserved)
