[Daniel shows the letter to Grace. This is what it reads:]

To my friend Daniel:
I knew you will find this eventually. Listen to my message; the password is something only you would know.
The first part is the name of your energetic friend.
The second part is the name of your calm friend.
The third part is the third name of God.
Access the data, and learn the truth.
