For Parents Weekend, the girls try to keep their visiting families from finding out every intimate detail of their dating lives.

It's Halloween! Kimberly tries to impress in class. Kacey debates when to admit she's a virgin. Bela keeps Taylor busy, and Lila hunts down a hottie.

Bela tries to break her dry spell, Kimberly takes a campus tour, Whitney's science project gets messy, and Kacey vies to be on Essex's "50 Most" list.

As Kacey preps for a special date, Kimberly takes her first nude. Bela hits a roadblock with Arvind, and Whitney prioritizes her needs.

With a protest looming on campus, the girls find themselves standing up for themselves, for what they need, and for each other.
