The series of emotional events that will decide Marin and Jack's future continues: While anxiously awaiting Marin's return to Elmo, Jack is caught off guard when someone from his not so distant past comes to town with a secret. Meanwhile, Annie is still upset with Patrick that he neglected her at Thanksgiving dinner, Jane and Sam -- aka Plow Guy -- spend romantic time in New York, Theresa and Ben wonder what's next for them, and Buzz faces a medical crisis.

Marin, who is suffering from writer's block and getting over Jack, volunteers to help at Elmo's fundraising rummage sale. Her publisher, Stuart, makes an unexpected visit to help critique her book's second chapter. Meanwhile, Jack tries to pick up where he left off with former girlfriend Lynn, Sara comes back to town and is surprised to see Ben and Theresa back together, and Patrick's storybook proposal to Annie goes awry.
