Lana and Sam talk about their current love life situations 

Well, he is thinking about dating. Maybe he just wants to make a good impression.

Believe me my step dad has done something like general lane did to his hair my step-dad is the same age as my mom and his hair would turn gray and white he would die as hair so it would stay the normal young color looking hair so the characters not alone here I know you're just making a point or something I'm just staying my knowledge of this of what it reminds me of.

Lana and John Henry look like they might have some sparks. At least, if the show gets a fourth season.

I seriously doubt Lana would go out with her friends father But I could see something happening between Lana and John.
