When Barney and Quinn start living together, Barney's reluctance to throw out any of his old possessions makes the gang doubt his faith in the relationship. Ted, Marshall and Barney hold their triennial `trilogy time' event, at which they watch the `Star Wars' film trilogy and try to picture how their lives will have developed in another three years.

Casey and Cappie are finally back together. Elsewhere, Rusty and Dale's argument comes to a head and the ZBZ girls prepare for `Song Fest'.

ZBZ tries to get back to number one whilst Lana tries to corrupt Rusty when she, Rusty and Cappie hang out together.

Casey volunteers to assist in planning a ball to raise money to rebuild the Gamma Psi house.

It's spring break and everyone is preparing to leave for another trip to Myrtle Beach. Meanwhile, Casey is anxious about her CRU law school application and Ashleigh lands an internship in New York.

Casey tries to finish her personal statement for law school and goes to Joel for help. Rusty takes charge when the KTs get new neighbours, a family.
