They're Both Just On Different Playing Grounds In Life Its Just Always Thrown Me Off - Tumblr Posts

This may be a hot take, but I don't think people would have such an issue with hankcon if:

Connor didn't have a "born sexy yesterday" complex. He's a detective android programmed mostly to understand crime scenes and solving mysteries, so he is mature enough to understand crimes, felonies, and morality (at a certain level). However, you can tell he doesn't have a good grasp on regular adult humor (or sex jokes), which was pretty much proven when Hank asked him if he knew where he could shove his instructions, to which he responds "No? Where?"

Hank didn't look like somebody's cigarette smoking, beer guzzling paw paw. Hank, if we'll just be honest, looks pretty...aged. not in a bad way, but the average person does not see much sex appeal in someone's cranky pop pop. I, personally, don't take interest in men that old, and I'm not making fun of you with seriousness if you do, but I just don't see it, and I feel like people would care less if he looked younger. (Saying this as someone who does think Clancy Brown was attractive).

It may be the age gap, but I think the maturity is also a part of it as well.
