Dave's song, "The Girls of Paradise", mentions all the current female guests on Paradise Hotel.
Zack checks back into Paradise Hotel as a visitor.
Alex checks out of Paradise Hotel.
Except for Scott, the rest of the men (Alex, Dave, Keith, and Tom) are all at risk of being voted out of Paradise.
The bad news is that one of the men is going to check out of Paradise Hotel.. but the good news, and most surprising is that Zack returns!
