Agree. Scroobal was very well-versed in the late '60s and '70s from the perspective of a teenager/young adult. I recall very distinctively he said if a woman in the late '60's goes out on unchaperoned date, likely to be ready for "sex". Now why would an 8 year old child know that?
If he's 51 years old, it means he's born in 1962/1963. In 1970-1980 he would be 8 years old to 18 years old. A little young in my opinion.
He's around 55 to 60 years old from the way he puts people down and belittles you if you fall out of favour with him.
