Adam warily watches a seemingly fine Kristina dig into the cake ordered in the event that she actually won the election. Despite losing, Kristina insists she's just fine and is looking forward to baking, family dinners and activities she couldn't do while campaigning. Later, Heather and Kristina share a goodbye hug - losing this race stung more than other campaigns on which Heather's worked.
It's like salt rubbed in an open wound when a "concerned citizen" passive-aggressively suggests Kristina fix a slide at the playground so Nora doesn't hurt herself. Even Gwen questions Kristina's cool-calm-and-collected demeanor - it's got to sting that she lost by only 947 votes. Kristina's true feelings finally come pouring out when she confides in Gwen that she thinks she could've won the election if she'd stooped to Bob Little's mudslinging level. Instead of a typical date night, Adam helps Kristina "get dirty," since she remained pure throughout the election. Like two teenagers, they chuck eggs and insults at a prominent Bob Little billboard. Kristina can't hold back a big grin.

Once this free love period of his life is over, it's over for good! Natalie's "no rules, no strings attached" sex doesn't fully appeal to Drew, so he tries to insert some rules: frat parties are her hook-up zone; his is yet to be determined.

But the next day like clockwork, there's a booty call knock on Drew's door... Much to his surprise, it's Amy.

Joel unenthusiastically agrees, proving he's turned a corner by leaving work early the next day to set up a family night pizza party.

Crosby and Adam have a serious talk with Amber about domestic violence; Amber must tell Sarah about the fight. Ryan waits for her at home, having called in sick to work.

Amber needs time to consider whether their relationship will work in the real world.
Shaken, Ryan spills the beans to Zeek over beer and a bonfire. The band has been baiting him - and Zack has no idea what's important in life! Zeek agrees, but what happened between the guys was important to Amber. Ryan miserably comments he often thinks he's not cut out for civilian life. As much as he hated Afghanistan, everything made sense and mattered over there - he can't seem to disconnect from that life. Zeek advises Ryan to decide in which world he belongs: alone in Afghanistan or married to Amber in Berkeley.
Amber finally turns up at Sarah's apartment to tell her all about Ryan's fight with Zack. Only after Amber asks does Sarah offer her precious daughter some advice: even though Amber's tough enough to stay with Ryan, it doesn't mean she's meant to.
