Fischer described the wait as the note was introduced and then held on to for the right moment. She thought maybe the showrunners would bring Chekov’s Note back for the wedding episode when Jim and Pam finally got married, but they showed great restraint and held it back until the very end of the show.

Yes, John Krasinski did write something for Jenna Fischer to read, and that tearful reaction is authentic, but it’s not a note from Jim to Pam. Rather, it was a note from John to Jenna as their nearly decade-long adventure together was coming to a close.

“I believe Greg (Daniels) suggested to John that he write a personal message. From himself to me. Just saying what our time together on “The Office” meant to him. Because we were wrapping up filming, we were wrapping up the series and we were all so emotional at that time, you know. So I’m on camera and I open up this note that John’s written me and I just start crying. I just start bawling. Probably the first take was probably not usable. It was the sweetest note and you know, on camera, Pam says, “I’ll never say what it said, but just know it was perfect.” Well, I’ll never say exactly what John wrote, but I will say just know, it was perfect.”

While we don’t know the exact words he used, it is absolutely adorable and totally fitting that this is the story behind one of TV’s most intriguing unsolved mysteries.
