Ehhhh careful. That line of thinking could easily turn into “I am the age that I say I am and I don’t care that you think Gary is a creepy pedo. My body is 8 years old but I feel like a 40 year old and Gary understands that!”
To your point. Age shouldn’t matter beyond that one transition from “legal guardian protects you while your brain finishes development” and “you are now legally an adult and in control (and responsible for) your own actions”.
I think this is why the US legal system actually gets this one pretty close to right.
Came to the comments to say this. Love that series. Wish they hadn’t moved to that follow-up series Star Force. Wasn’t as good, imo.
