His first day with Willy was Willy bringing him out of the orphanage and to a small restaurant for lunch.What was Joe's first day with Willie like? What did he do with him, where did they go? And also, what was his last day with Willie like? How did they say goodbye, or did they even get to?
Willy softened Joseph up with small magic tricks before they spent the afternoon asking each other questions and getting to know each other.
Joe's last day with Willy was Willy sending him off to go on his own adventure and find his identity as a person and a grifter/thief. Willy was uncharacteristically sentimental that day as he knew it was the last time they would see each other.
Willy died during the year Joseph was travelling.
Willy's last words to Joseph were ironically "I'm proud of you son. Go get'em"
It was only standing over Willy's grave that Joseph put the pieces together.
