Wow I rewatched episode crushed of Full House tonight and damn huge problems.
I'm pretty sure DJ was not the age of consent so Danny besides asking why she believes DJ is dating the Singer Tommy Page also never brought up the age difference problem.
Very surprised Tommy didn't inform her before it started spending the day with her is friends activities not dating so a misunderstanding could not happen.
Also if a person is seriously involved with another person it's playing with fire if the person kisses another person on the cheek.
