According to Showtime, this episode contains nudity.
Not totally 100% on this, but it sounds like Dora Madison Burge (from the TV Show Friday Night Lights) will be topless. According to an IMDB review by Jkrishan, there is a scene in a topless sports bar and it is implied that is Masuka's daughter.
"The only scene with nudity is set in a topless sports bar. And yes, if you're a fan of a particular new character... :)"
"The relationship between Masuka and his daughter also begins to evolve. Sorry, there’s no big revelations/mysteries to speak of here. That said… There is a fun “character comeuppance” for Masuka that is fitting after 7 years of ogling the hot ladies."
