There were certainly mature students when I was a young student, Ronald, but Dean wasn’t a mature student, he just dressed like someone 20-30 years older. This was inadvertently exacerbated in his early appearances by the organic style of Giant Days’ brush inking (issues 13-34) which took some of the sharpness out of Max Sarin’s pencils. If you see him in later issues where Max is inking, he’s not as jowly.
