Epilogue
In the year 2030, Robin Stinson sat on the floor of her and Barney's living room, looking through photo albums.
Robin had gotten nostalgic, especially since Ted was telling his kids how he met their mother. Robin loved Ted's wife. She fit into the group perfectly, as Robin had when she first met them twenty-five years earlier.
Three days after Annabelle's birth, Robin and Barney had been married in City Hall by the Justice of the Peace.
Robin, Barney, and Annabelle had moved in with Ted shortly before his thirty-first birthday. Ted had been in a car accident and needed some help. Lily and Marshall, parents to a newborn themselves, couldn't do it. After Ted's thirty-first birthday ( and the Goat Incident), he had recovered.
The Stinsons had soon moved back into Barney's apartment.
Upon learning of Robin's second pregnancy, the two began looking for a house. Ted had just met his future wife, and they were also looking to leave the city.
The couple moved to a four bedroom house on Long Island. On June 17th, 2011, Robin and Barney welcomed a son they named Aidan James Stinson. Two year old Annabelle had adored her new baby brother.
Robin and Barney had agreed their family was complete following Aidan's birth, but there had been a surprise waiting for the couple.
Robin was forty-three when she unexpectedly became pregnant for a third time.
She gave birth on August 5th, 2021 to a little girl. She was named Emily Jayden Stinson.
Emily was their final child because the two were older.
Annabelle was now twenty, Aidan was eighteen, and Emily was nine.
Robin and Barney loved their family.
Marshall and Lily welcomed their first child, a son, named Matthew Theodore Erikson on March 27th, 2009.
Matthew and Annabelle were now dating. They had been best friends all their lives. The two had been together for six years. Some even referred to them as the second generation Marshall and Lily.
Three years later on May 12th, 2012, Marshall and Lily welcomed twin daughters.
They had been named Melia Lily and Grace Robin Erikson.
Less than two years later Lily and Marshall welcomed Andrew Barney Erikson on July 15th, 2014.
On September 13th, 2016, Lily and Marshall's fifth child-their final baby- was born. It was a little girl the couple named Gillian Michelle Erikson.
Shortly after Gillian's birth, Marshall had proved the existence of the Loch Ness Monster. He had become instantly famous and rich.
He also wanted to prove the existence of Bigfoot, but that was taken away from him. In 2025, a group of hikers in Oregon had proved that Bigfoot was real.
Like Annabelle, Matthew was also twenty. Melia and Grace were now seventeen, Andrew was fifteen, and Gillian was thirteen.
Ted and his wife had married in 2012. Their daughter had arrived in 2013, and their son followed in 2015.
Life was good.
Robin Stinson's life had changed dramatically one night because of Sandcastles In The Sand, but she wouldn't change a thing. She was happy.
The End
