I would write a "love letter" which goes something like this:
You know I would never give you up, or let you down.
You know that I would never run around and desert you.
You know I have never made you cry, and I won't say goodbye yet.
I love yo and I would never tell a lie and hurt you. xxxx
I hope you find this, and make it out okay. xxxx
Love, Lene (his wife)
This would be followed later in the campaign with you encountering a Rick Astley zombie, in a room with the track in question playing in the background.
