While at brunch, Kyle relives how he broke Holly's heart at the prom.
As if having Duncan around every day doing construction on her home wasn't enough, Nicole faces her worst nightmare when her husband, former pro-football player Yonk Allen, invites Duncan to test his new video game and tag along for an Eagles game. Meanwhile, Holly's obsession with getting her daughter, Oprah, into Kyle's school becomes unbearable for Kyle and Aaron when she starts dropping by their home unannounced. Also, Richie and Lina attempt to go on a second date while Kat sets Ethan up with one of her friends.
After questioning her behavior, Ethan is forced to prove that he is not a wuss when Kat dares him to test every yogurt flavor at a shop without buying anything.

In spite of being threatened by a bee and being coaxed by local law enforcement, Richie refuses to leave his car as it provides the only safe haven from the chaos that currently surrounds his life.

Meanwhile, Nicole attempts to get Yonk to take better care of himself by proposing that the both of them go on a diet, but she is soon tempted when Duncan asks her out to dinner.
A wicked snowstorm hits Philadelphia, trapping the class at each other's homes. This wouldn't be all bad, except the snowstorm happens to hit on Valentine's Day and the class is unable to spend the day with their significant others.
Nicole is stunned that Duncan and Richie are finished working on the house, and she suddenly realizes how much she'll miss seeing them every day. Meanwhile, Ethan decides to dump Palmer, but backs out at the last minute.
