The first action is: "Nick found the key that I had lost last week."
The second action is: "They had spoken to him before they went home."

However, it seems that there is a numbering discrepancy in the provided sentences. After the second action, the numbering jumps to 6, and there is no sentence numbered as 4 or 5. If there are more sentences, please provide them so I can help you determine the first and second actions.
