Emilie's Grandpapa tells Albert the long sad story of Emilie and Joey. After one final hearty cry, the old man offers to sell Joey to Albert for a penny and a promise: "that [Albert] will always love [Joey] as much as Emilie did" (21.16).
Of course, Albert agrees. He buys Joey and travels back home.
We can't believe it. Joey lived 'til the end. Okay, now we've got tears of joy.
Back in the village, Joey is reunited with old Zoey and lives happily ever after with his new family. Sigh.
