after mac comes out he starts watching rupaul's drag race cause he's a gay man and gay men like drag but very quickly he realizes he's not interested (he was into the pit crew tho) so he stops but dennis who had been lowkey watching whenever it was on screen WAS into it so he starts watching it by himself and that's how you get dennis yelling at the screen during the lip synchs for your life cause the queen he's supporting isn't serving enough cunt
