Random thoughts and nitpicks that occurred to me:
a) I get not hearing a whole word but missing a letter at the end of the word? Maybe you wouldn't hear, friend, but you should've heard the s in Father's.
b)This misunderstanding set off a whole set of jokes about stepbrother, but shouldn't it have just been brother
c) I hope Ariana and Enzo know about Erryn's father so they can say something like, "O yeah, you're Melissa's daughter."
d) Being what happened to her in the past, shouldn't Val have been freaking the fuck out at Zack holding her in the air trying to steal a smooch?
e) I wonder if Zane did what some people do when trying to get into a girl's pants: mimicking them. "OMG, Erryn, you want to be a teacher? me too!"
f) The Monroe parents are laid-back. Neither daughter was quiet, yet Enzo didn't trip at all when his daughters got smashed in his house.
g) MC's an idiot if he's playing the scumbag why the hell would he be taking his dates to the beach where everybody goes.
Im sure I'll think of more later but that's it for now
